AutoCAD 32-bit on Windows 7 RC 64-bit???

[Jaelin]

Okay guys, got a few questions here. I've searched the forums and found partial answers to some of this but not fully what I'm looking for so please forgive me if this has been asked before.

Situation: I'm working with AutoCAD Civil 3D Land Desktop Companion 2009. At work: Windows XP 32-bit At home: Windows 7 RC 64-bit. My DVD's state that they will work with Vista/XP 64-bit in 32-bit compatibility mode only.

Questions:

#1) Does anybody have any experience with AutoCAD 2009 on Windows 7 RC?? Will it work??
#2) If it will work, then will my 32-bit work effectively on the 64-bit Windows 7??
#3) This may be a stupid question here but I am not up on the differences between 32-bit and 64-bit. Is there any compatibility problems with bringing .dwg files back and forth between 32-bit and 64-bit operating systems??

That's it for now. Any insight into this would be appreciated. Thanks.

Thanks.

- I dont see a reason why not. I have been using AutoCAD ADT 2004 on windows 7 Beta (Build 7000)

I dont have the answer for the other 2. Sorry :(

#2) If it will work, then will my 32-bit work effectively on the 64-bit Windows 7??
I dont think it will, but the dvd comes with both th 64 and the 34 bit versions, if you have the cd and not the dvd you should contact your local reseller to get the 64 bit cd

No problem, thanks for the reply to that one. That helps.

I have the DVD for both 2009 & 2010 and neither one of them includes the 64-bit version. All the DVD's say on them is . . .
Windows Vista (64-bit) and Windows XP (64-bit) are supported in 32-bit compatibility mode only.

I'm going to try the installation tonight to see what happens. Worst case scenario the program sticks its tongue out at me and says you can't do this. I'm not sure where to set it up in 32-bit compatibility mode but will find that. Thanks for the help guys, any other ideas would be appreciated. I'll update with results of the installation attempt in the morning.

Would they just give out a 64-Bit CD?

No problems. I'm on a 64 bit machine at work, but the rest of the office is on 32 bit. They have no problem opening and working with my drawings and I have no problem with theirs.

[ReMark]

F.Y.I. - Microsoft recommended specs for systems running Windows 7.

1 GHz coprocessor (32-bit & 64-bit systems)
1 GB RAM (32-bit); 2GB (64-bit)
16GB free space (32-bit); 20GB free space (64-bit)
Support for DirectX 9 and a graphics card with a minimum of 128MB vidRAM

[Jaelin]

Would they just give out a 64-Bit CD?

Hmmm, good question. Especially since we're on subcription here, they might send the 64-bit version since we already have the 32-bit. That's a viable option to look into. Anybody know for sure on this??

Cool. Thanks for the info.

BTW, installation didn't happen last night though I did learn a valuable lesson and that is . . . if you want to install ACAD on a computer at home typically it helps to remember to take the DVD's home with you. :P Anyways, now I'm feeling like the NASA Endeavor Space Shuttle launch . . . we will try again this afternoon. :)

If you’re on subscription you would be able to simply log into the autodesk subscription center, and download all the software you’re entitled to.

We’re on subscription as well, and the very same day that 2010 came out, I was able to download all install files. I downloaded 64-bit for my laptop at home, 32-bit for our work computers.
While 32 & 64 bit versions should be included on the DVD’s, for the downloaded files you have to choose if you want to download the 32 or 64 bit version. All software we have on subscription has that option (Inventor suite, Acad Mechanical, Acad Electrical). I’m sure Civil 3D will have that option as well.

Hmm, that's interesting didn't know you could do that. However, I log into th subscription center and all the options I get is to download the 32-bit. No 64-bit downloads are available. I wonder if the subscription is actually tied to 32-bit or 64-bit or both depending on which service your subscribed to??

Either way, I installed AutoCAD night before last and worked some more with it last night. Everything seems to be working fine with no problems other than it won't insert Mr. Sid files correctly from Map which is does here at work. It's telling me that there are problems with the coordinate correlation so that's something I'll have to figure out but something that I can live with for now. Thanks for all the information and help guys. Will update if anything goes awry with it.

When I ordered the trial DVD of ACAD-A 09, Autodesk sent me both (32 and 64 Bit). I only use the 32, but if you need 64 I can mail it. I live in Tampa Florida.

I assume by ACAD-A you mean Architecture. I use Civil 3D Land Desktop (at least in 2009 i d0, now I gotta move to plain Civil 3D when I move to 2010) so it wouldn't help me though I appreciate the offer. Though now that I think about it, if it's only the trial and you don't need/want it, I wouldn't mind looking at Architecture . . . let me know.

On another note, I'm not too far from you, I work in Bartow, but live over in the Riverview/Brandon area. So 30 minutes tops probably.

[CADMASTER1128]

Well, if your Brandon it not to far from me. I live up 75 in New Tampa. And ACAD-A (64 Bit) is all yours!

Sounds good.

From my experiences most 32bit applications will install on a 64bit machine, but it'll just run as 32bit. :)

**EDIT** I forgot to add that its weird because Autodesk doesn't let you do that.

Well, that's the strange thing, I keep hearing that Autodesk doesn't allow me to do that but for some reason it's working for me. I am new to dealing with 64-bit when I downloaded the beta of Windows 7 64-bit. Then I upgraded to the Windows 7 64-bit RC {Release Candidate}. But I loaded AutoCAD Civil 3D Land Desktop Companion 2009 32-bit and it seems to work fine. :?: I have only had about 20 minutes of use time on it to test it but everything seems to be going good. So I'm kinda confused :? about what's going on. Am I going to run into problems later or should it even have installed the program?? Not really sure right now. We'll see what happens as I do some drafting on it over the weekend. I'll update if things are not working but for now it seems like everythings kewl with it.

And, you know, I honestly don't care if it upgrades the performance to 64-bit. If it keeps the performance at 32-bit thats acceptable to me as long as I'm able to use the program at home to cut down on the amount of commute time to work when I have to work overtime. With a 40-mile trek to work each way it would be nice to be able to work from home but I don't want to downgrade my OS to 32-bit unless I have to.

We'll see what happens.

Good article there. Fills in a few of the gaps of what I thought about 64-bit.

Just as an update. I ran the AutoCAd 32-bit over my 64-bit computer and O/S over the the weekend and I did not run into any problems. Looks like its working fine.

Hows the new AutoCAD working out?

Hows the new AutoCAD working out?

Lol, on Sunday afternoon I got called in to work to prepare for a last minute "emergency" :glare: project on Monday. Then with the massive overtime I've had to work :bloodshot: that came with that project I have not even had time to load the ACAD-A. I hope that the project winds down by Saturday so I load the program then. Thanks again for it though. Will let you know how it goes. Later.

Wow, sounds busy with a lot of sleepless nights. Take your time with installing it. Hope you enjoy it.

[ChrisB]

I need to install a 32 bit version of acad map2010 on my 64 bit os system. I already have the 64bit version installed but require the 32bit version in order to run a 32bit app within acad. there is no 32 bit app available at the moment. I know this could be done in previous versions even up as far as acad 2009 by modifying the msi, from my research online. Have not been succesful in finding info on doing the same thing with 2010. Really in a bind and need a solution. Can anyone shed some light on this please. I have to run a client supplied custom cad standards checker (32bit app) and am unable to do so with the 64bit os as it will not allow me to install teh 32bit acad. Your help is appreciated. Have a good day!

[ReMark]

You may have to use XP compatability mode.

[ChrisB]

Use XP mode with current 64bit install? I have not been successful installing the 32bit version. I'll give that a try. Thanks, I'll let you know how I make out.

[ReMark]

I have a 32-bit and a 64-bit version of AutoCAD on my new (64-bit) computer and both run with no problem. I'm using Win7 Ultimate as my OS.

[ChrisB]

ok, almost the same, I'm running win7 professional. I'll restart and try again to install teh 32bit app. Sounds like there may be a glimmer of hope yet. Thanks

[gwizzer]

Hi ReMark,
you indicate you have 32 bit AutoCAD on your 64 bit OS ...

Is this AutoCAD 2010 32 bit or AutoCAD 2008 ? and is the 2010 the 64 bit version ?

The problem seems to stem from having 32 bit applications needing to run on AutoCAD. These will not work on 64 bit versions of AutoCAD and 2008 appears to be the last version that will run with any stability on a 64 bit OS.

While I can get 2009 x32 on a x64 bit OS installed it is so unstable that it is unusable. (and I guess that is why Autodesk prevent us from doing that !!!)

Cheers

[ReMark]

I have AutoCAD 2004 (32-bit) running on my system. It was a test to see if I could do it. I also have the 64-bit version of AutoCAD 2010 running on it as well. I've had no stability issues with either program.

[gwizzer]

OK thanks, that is what I guessed ...

I have 2008 x86 on Windows 7 x64 which works well, but the applications I am running requires a x86 version as opposed to an x64 version ...

gw

[gwizzer]

I thought I would update you on what I have discovered ...

You can modify the Autocad installer to install a x86 version on a x64 OS, but I did have issues connecting to a network server. However, it did work.

I think it was on this thread though that someone gave the real clue away. Autodesk have already done this for us.

It is called Civil 3D x64. It would seem that Civil 3D requires some 32 bit components and Autodesk have not got round to updating these yet ... so to appease people they have done all of the modifications and install a x86 version on AutoCAD on your x64 bit OS.

You need to download the latest patch .... but it works and my x86 apps run on top of it as expected. Windows 7 reports the AutoCAD as a 32 bit app.

I did not need to modify anything and it also turns out my x86 apps recognised Civil 3D as a valid version.

There is also a start menu item called "AutoCAD Civil 3D as AutoCAD 2010", so you do not get all of the Civil palettes ...

This website, www longbowsoftware com, explains all the pitfalls of using AutoCAD 64bit compared to 32bit and also provides a tool which allows your AutoCAD 32bit to run on Windows 7 64bit.

[tomhurns]

I've posted before on this, but I want to spread the word! :-) I'm using my AutoCAD 2008 and 2011 32bit on Windows 7, 64bit. I used this software to allow it... www.longbowsoftware.com Enjoy!

[ReMark]

Pitfalls to using AutoCAD 64bit? Come on, give us a break. The only pitfall is when someone tries to run a 32bit app on a 64bit machine and they don't know what they're doing. A little preparation goes a long way. Reminds me of those people who still insist on using a printer purchased in 1985 with an OS released in 2009.

[eklektikus]

I realize this thread is a tad outdated but I'm reading past postings in preparation for ordering a new computer and going to a 64-bit OS. ReMark, you state in the previous post, "The only pitfall is when someone tries to run a 32-bit app on a 64-bit machine and they don't know what they're doing". Does that comment cover Autolisp's also? I have a lisp called "Flatpipe" that was given to me and I run it quite often in my line of work. Is there a chance that this lisp will not run, currently on 32-bit, when I switch over to 64-bit? Thank you for your response.

[ReMark]

eklektikus: Your lisp routine should still work. My only concern would be if you said it was created back in a much older release of AutoCAD. AutoDesk does occasionally make changes to autolisp commands and sometimes users find that old routines malfunction when they try to use them in a new release.

In regards to my comment re: 32-bit apps on 64-bit machines I'll cite but one example. If the user tries to load AutoCAD 2004 32-bit on a 64-bit computer in all likelihood Express Tools will not load. Also, Windows 7 will install 32-bit apps in a different folder than the one used for 64-bit apps and in the case of AutoCAD the support folder/file paths will be much different. Those used to the old paths will be surprised the first time they have to make any additions or deletions to them.

[eklektikus]

To be totally honest, ReMark, I have no idea in what release this "Flatpipe" lisp was created, who created it, or if there are "updates" to it. I know that it ran in the 2005 release that was "loaned" to me at my last job and in the 2010 release that I purchased when I went to "self-employed". There is still so much to learn regarding AutoCAD! Thank you for your prompt reply though.

[ReMark]

The best advice I can give is try it and see what happens. If it does not work and the lisp file was not compiled then you can post it here and let some of our very knowledgeable lisp programmers take a look at it and see if they can pinpoint what the problem may be. However, we make no promises. Remember, we're all volunteering our time, efforts and knowledge. Get back to us either way and update us on your situation. I recommend you start a new thread in the appropriate forum. Thanks and good luck.

[longbow]

Remark, with all due respect, the issues you are talking about are due to enhanced security in Windows 7 in general, not that 32bit apps are toast on 64bit. Older versions of AutoCAD write to, what Windows 7 (and Vista) consider, sensitive parts of the machine like the HKLM registry and the Program Files folder which since Windows Vista requires elevated user access to do so. This was all brought about by the wave of virus's that hit Windows XP.

Also, about your comment that anyone running a 32bit application on 64bit Windows doesn't know what they are doing, let me give you an example - Microsoft Office 2007 only came in 32bit, and that runs fine on Windows 64bit does it not? Now are you saying that Microsoft themselves don't know what they are doing? The bottom line is that Windows 7 64bit comes in the box with FULL 32bit support, and in contrast, Windows 7 32bit comes in the box with FULL 16bit support.

Finally, regarding running LISP on 64bit Windows - LISP is an interpreted computer language, meaning that cares nothing about pointer sizes (64bit or 32bit), however, if your LISP code uses ActiveX (vla-) functions then you may have some performance hit because AutoCAD 64bit ActiveX runs out of process, whereas AutoCAD 32bit ActiveX runs in process. So ANY LISP code that works on 32bit WILL WORK FINE on 64bit, unless it uses the COM ActiveX API, in which case you may see a performance hit.

I hope this explains a little more the mystery of it all.

[ReMark]

I think you have responded to a different thread than the one I posted to. In any event, I thank you for your concern and for providing those additional pieces of information. Have a sparkling day.

[longbow]

Actually Remark, I think judging by your reply a second ago, that you might have actually meant running a 32bit DLL (app) *inside* of 64bit AutoCAD - my mistake, here's your quote - "REMARK:The only pitfall is when someone tries to run a 32bit app on a 64bit machine and they don't know what they're doing."

Have a good day too. Nice chatting

how can i install 32 bit autocad 2008 or 2010 in 64 bit windows 7????

[ReMark]

I've personally loaded 32-bit version of AutoCAD 2004 on a computer running Windows 7 Ultimate 64-bit.

What version of Windows are you running?

When installed the program will be found in the Program Files (x86) folder and not the Program Files folder which is strictly for 64-bit apps.

If you run into problems you can always use Longbow Software. See this.....http://www.longbowsoftware.com/

The single user license for Longbow Converter V4 is $40.

[waterprez]

autocadd does have a solution for this...
i have done it and have had now problem running the 32bit on my xp64 bit machine.....

Updated Workaround instructions for 64 Bit OS Install.Options

1. Download and install Orca from Microsoft.
2. Copy the installation files to your hard drive or a network folder.
3. Backup the files ACA.msi and Setup.ini
4. Edit the ACA.msi with Orca and delete the action found in the table
"InstallExecuteSequence" that is called "CheckFor64BitOS" Delete the same
line under table "CustomAction"
5. Save and close the ACA.msi
6. Edit the Setup.ini with Notepad. Delete the line under
"#==================== Platform Requirement" that is labeled
"PLATFORM=NO_WOW_64_PROCESS"
7. Double-click the Setup.exe and you should be able to install without any
problems.
8. Some support paths under the "Files" tab of the configuration dialog box
have incorrect paths. The installer adds and extra "\AppData\AppData" to
some support paths located in the user profile. For example the Main
Customization File's path is listed as
"C:\Users\%username%\AppData\AppData\AppData\Roami? ng\Autodesk\ACD-A
2008\enu\Support\ADT" when it should be
"C:\Users\%username%\AppData\Roaming\Autodesk\ACD-?A 2008\enu\Support\ADT"
Fix the incorrect paths, hit apply, and you are good to go.
I wonder why the ADT team chose to disable 64 bit installs. The program
seems to function fine in Vista 64 bit. ADT 2006 and 2007 installed without
a hitch on this same system even though you had to set them to run as ADMIN
in order to be able to use them, so I am not buying the whole "the ARX
programs don't work with 64 bit" argument. I switched to Revit a few years
ago anyway, but it is a shame what they are doing to ADT. Peace out. ....
