Configured Heidi driver cannot be loaded

[MikeP]

Why do I get this message every morning? "the configured Heidi driver cannot be loaded. Switching to default software driver." This happens every morning. My computer and autocad stays on overnight. What is happening throughout the night?

[Tiger]

I know when it happens - beacuse it happens to me, it's beacuse your screen saver gets going.

That's not the real reason, I admit, but I have searched and search for this answer, never found an answer - so I beg you, please come back here if you find the solution!

Maybe, if we turn off the screen saver. I mean I work on my comp 90% of my day, and I turn off the monitor when I go home. So it almost seems pointless to have it on.

My guess is it has something to do with the display driver. There are two Heidi display drivers: Heidi Software and Heidi OpenGL. Are you using a 3D graphics card utilizing OpenGL? What graphics card are you using? Do you have an AutoDesk Subscription?

[Tiger]

MIke, can I ask what you are working on? The files that you have, are the 3D by any chance?

THe reason I ask is because I used to have this happenening to me all the time, but then it stopped and I'm trying to figure out what the difference is. And the only thing I can think of is I was working on a 3D construction at the time - and since that was done, I can't remember this happening anymore.

Had the same problem here a while ago, this is the response I got from Acad support dated Jan 25, 2008.


Thank you for contacting Autodesk Support. It appears that this is being caused by Google Desktop. Development is aware of this and it looking into the specific cause and a permanent resolution.
In the meantime, please confirm that you do have Google Desktop installed. If you do not, please let me know and we can continue troubleshooting. If you do have it installed, please uninstall it, reboot your machine and confirm that it resolves your issue.

95% of what i do is in 3D.


and no i do not have google desktop

[Tiger]

No, no Google Desktop for me either.

HAv you tried just having AutoCAD on, but a blank file?

I guess you're both hard of hearing.

Are you using a 3D graphics card utilizing OpenGL? What graphics card are you using?

[ReMark]

So far my searches regarding the error The configured Heidi driver cannot be loaded..." have yielded various answers to the problem. They are, in no particular order:

Download and install the latest Service Pack.
Reinstall DirectX from the product CD.

Try switching from Direct 3D to OpenGL via 3DConfig, Manual Tune button.

Switch to software graphics.

Update your graphics card drivers to the latest versions.

Turn off hardware acceleration. Exit AutoCAD. Open AutoCAD and turn hardware acceleration back on.

Possible conflict with Netmeeting's remote desktop sharing. Disable this feature (in reference to Mechanical Desktop).

Choose your poison.

Personally, if either of you have AutoDesk Subscription I'd recommend getting on the horn to them and file a tech support request. That's one reason why you 'pays yo' money' as the man says.

now that you mention it, yes, I have felt a bit of a tightness around the ears lately, aren't you suppose to have cotton in there? o:)

I have no idea what graphic card I have, except that it's one from the list og Autodesk approved ones. And I switched from OpenGL to DirectX a bunch of times while I was having this problem, it didn't matter.

The point is that I don't have the problem now, it never showed up again when I stopped having a 3D-model on the screen.

The world is flat afterall! Thank God.

Ofcourse it is, and don't forget the elephants. 8)

Hello all having trouble with civil 3d 2010 again... Running windows xp -plot and get fatal error and close drawing. Help help help........thanks nik

[magic_man1]

This is a very strange error indeed. We have just upgraded our machines several weeks ago (performance wise as well as CAD software Building Systems 2006 to MEP2010) and until this morning I had only had this error, maybe twice on my upgraded machine. Now, this morning, I seem to get this error with every drawing, including those that I have opened in the last few days, without error.

Facts:
-None of these have been 3D drawings (simple Xrefs, linework, blocks, etc.)
-One of the first things I did after my PC upgrade was turn off the screen saver (still shows as off)
-This seems to be about as fresh of a MEP2010 install as I can think of, being only a few weeks into this install.
-No Google Desktop on this machine


P.S. I'm guessing iTunes is somehow causing this.. (that software is the devil)

[Skeeter]

This problem is caused by the 3D accelerator. Type in 3Dconfig, go to manul tune and turn it off.

[missaka]

Set the system to a earlier restore point. This restore the settings to an earlier day and cancel out the new changes you made.

Setting the Restore point_
Start> accessories>SystemTools>System Restore.

Hope this helps.

been using auto cad 2011 lately and i had the same problem ever since, just did what skeeter said and *poof*, no more errors..thanks skeeter..

That is just a way around the problem. You should really try to find out why all of a sudden you need to turn off hardware acceleration.

Do you have the latest driver update from Autodesk? What graphics card are you using?

i see what u mean, this really aint the proper solution for this type of problem, thanks for opening that up.

if you mean by "latest update from autodesk" is the "update" located on the 3dconfig tab then yes, i clicked that and it said i now have the latest update from autodesk but if there are others then no, the on in 3dconfig was the only one i tweaked regarding updates.

im trying to find what graphics card i am using but toshiba online only gave me this info regarding graphics. qosmio x505 lap top uses:
NVIDIA® GeForce® GTS 360M with 1GB GDDR5 discrete graphics
memory, plus up to 1274MB dynamically allocated shared graphics
memory using NVIDIA® TurboCache™ technology.
o Total Available Graphics memory 2298MB

i dont know if these helped at all since i dont know if this is the "graphics card" you stated.

thanks a lot slw210, any remedy on this is greatly appreaciated.. (i'm really out of ideas on this one..:()

[SLW210]

Go to Autodesk site and get the latest driver they have tested. I posted in your other thread for 3DS Max and provided a link to do a complete uninstall/reinstall.

[AleksP]

Thanks for Skeeter answer. Type 3dconfig in ACAD prompt. It helped.

[William Ferguson]

Same thing happened to me. Something about recognizing the Heidi file.

[MILES9X]

I've been researching this on and off for about 2 months. The latest information that I have found is this. AutoCAD does this intentionally, when your computer enters into sleep mode or the screen saver comes on. It does this as preventative maintenance in order to prevent a crash or lock up of the system. From what I can gather, you can disable sleep/screensaver, close out of AutoCAD when you are away from your computer, or you can live with it.
NOTE: Beginning with AutoCAD 2011, they added an icon in the lower right tray that allows you to easily toggle hardware acceleration back on, so it should save you a few steps of going into 3DCONFIG.

Here is the source of my information: http://forums.autodesk.com/t5/AutoCAD-2012/Heidi-Module-load-error/td-p/3235064

***pasted from above:

There are various suggestions posted on the forum on this issue. I understand that when launching AutoCAD 2012, it shows the error "Heidi Module Load Error. The configured Heidi driver cannot be loaded. Switching to default software driver."

After a bit of research with our development team the original error in this case with the Heidi Module error is a built in safety net. What happens is there is a known issue with Direct X 9 that causes a disconnect between the video card and the operating system when going to a sleep or screen saver mode. AutoCAD disengages from the video card Heidi module when this problem occurs. This is why you get the error.

AutoCAD does this to prevent a crash and loss of information. If it did not disconnect from the Heidi module and use its internal graphics AutoCAD would crash.

Basically this is an installed safety measure to prevent a crash with a known issue between the OS and the video card. Only certain cards have this particular issue when going to the screen saver or sleep mode. While they work properly otherwise this error message is nothing more than an alert and annoying. When the computer comes back from sleep the video card and OS reconnect and everything is put back to normal.

Heidi errors like this have to do with the video driver on your system. Often simply uninstalling and reinstalling the video driver will fix the problem. Aside from getting the current driver from the manufacturer's web site, you can also check your video card and driver against those that we have tested and certified:

*Update graphics cards drivers

*You could also try going to your Options..."System Tab"...Select "Performance Settings"...try turning off Enable Hardware Acceleration...

*Perform a Windows Update to install the available fixes from Microsoft.
