How to prevent AutoCAD from opening another AutoCAD?

When opening a another DWG file from explorer, AutoCAD opens another AutoCAD window.

How do I prevent this from happening?

Already tried SDI and it doesn't work.

Any help?

Thanks,

erona: Have you updated AC 2007 with its latest service pack?

When did the problem first occur?

You might have a bad or corrupt aclauncher.exe file. However, before we go there let's check something else. Please follow the instructions exactly. This gets a bit involved.

Open Windows Explorer.

At the top of the screen click on Tools then Folder Options.

In the Folder Options dialog box click on the File Types tab.

Scroll down the list of Registered file types until you find DWG and highlight it.

Click on the Advanced button in the lower right hand corner.

In the Edit file type dialog box, under Actions, highlight the word "open" then click on the Edit button to the right.

In the Editing action for type: AutoCAD drawing dialog box look at the entry for Application used to perform action:

Write down the full path displayed there exactly as you see it. It will start with C:\Program Files\....

When done click on the Cancel button in each window until you are back in Windows Explorer where you first started.

Come here and post what you wrote down.

One other piece of info I need. Search your hard drive for aclauncher.exe and tell me the date on it.

I'm not sure but I guess I got lucky.

Under the Editing Action for Type: AutoCAD Drawing > Application used to perform action: there was these quotes on %1 which appeared "%1". I removed the quotes and went back. Tried to open another DWG file in windows explorer and viola! Its fixed!

Thanks ReMark!

You're entirely welcomed, erona.

However, that wasn't quite the fix I was going to suggest but if it worked then why knock it, right? Let us know if the problem resurfaces. I'd be interested since this is the second time in a week or so that someone has experienced the exact same problem. First time out I had no clue as to where to start looking.
