SYMPTOMS

When the Visual C++ .NET IDE tries to convert a project (.dsp) file from an earlier version of the product to a solution (.sln) file, the IDE may stop responding (crash) and the environment may close.

CAUSE

The .dsp file contains environment variables $(<ENVVAR>) in a source path. Although environment variables were not supported in the .dsp files, they could have been added outside of the Visual C++ project environment to customize the project. Visual C++ .NET does not recognize the environment variables during conversion, which causes the IDE to stop responding.

RESOLUTION

To resolve this problem, do one of the following:
•Use a text editor, such as Microsoft Notepad, to edit the .dsp file and change the environment variables to the actual or relative path.
