I'm using Progecad 2010 professional on Windows 7. When trying to open *.dwg file from windows explorer I get a Runtime Error that shuts down Explorer and inturn doesn't open Progecad.

Any thoughts

Thanx for the Reply

The OS is Windows 7 Professional

Drawing (*.dwg) files are able to be opened by double clicking the name in Windows Explorer which in turn launches Progecad
Normally, in both Windows XP Pro and Vista Business Operating systems. (Same File used for test)

In Windows 7 - double clicking the drawing file within windows explorer returns a
Runtime error
Program C:\Windows\Explorer.EXE

-pure virtual function call

Then closes Windows Explorer and Restarts Windows Explorer. Progecad does not get launched as for the other operating systems for the same procedure

According to your description, the crash is actually not in progeCAD but in Windows Explorer. This is a standard Windows C++ runtime error which is described here:

According to this page, this is a common error and the main reason is somehow the program or process being corrupted: ... id=3724670

I would suspect a corrupt installation of Windows, problem in Windows registry or even a virus.
