opening a DWG from windows explorer launches new session

[smiller.74700]

On one of my users workstations whenever he browses to a DWG and double clicks to open, it launches a new session of AutoCAD, even if there is an active session already running. Single-drawing compatibility is not checked.

We are running AutoCAD 2002 with SurvCADD XML2. No other user is having this problem. This is a fresh install.

Thanks

Try setting the system variable "SDI" to 0. If it is set to 1, it turns off multiple-drawing interface.

I did that and it was already set to zero. That does the same thing as checking the single drawing compatibilty mode in preferences.

I found the problem. It was #10 on this published fix from Autodesk website:

Issue


When you try to open a drawing from Windows Explorer, the following error message is displayed:

AutoCAD Message:
Cannot find the specified drawing file.
Please verify that the file exists.

Solution


Open Windows Explorer.
On the Tools menu, click Folder Options.
In the Folder Options dialog box, click the File Types tab.
Scroll down the list of file extensions to DWG and select it.
Click Advanced.
In the Edit File Type dialog box, under Actions, select Open.
Click Edit to open the Editing Action for type dialog box.
In the Application used to perform action box, the path to the acad.exe or the aclt.exe file is displayed.

The following text should be at the end of the path in this box:

"%1"

If %1 is not in quotation marks ("%1"), the error message is displayed when DWG files are opened from Windows Explorer.


Add quotation marks around the %1 ("%1").

Make sure the Application box in this dialog box is either blank, or has the value acad (for AutoCAD® software or products based on AutoCAD) or aclt (for AutoCAD LT® software).

Click OK in each dialog box to accept the changes and close the dialog boxes.

The error message is no longer displayed when opening a drawing from Windows Explorer.
