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.
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.
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.
Install the fix for this problem.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Visual Studio.Net service pack that contains this hotfix.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
Steps to Reproduce the Behavior
Use the Microsoft Visual C++ 6.0 Application Wizard to create a Microsoft Foundation Classes application.
Close the project.
Use Notepad to open the project.dsp file that you created in step 1.
Scroll down and note that # Begin Group Source Files is followed by several lines of text that end with # End Group.
Paste the following three lines of code above # End Group, and then save the file.
# Begin Source FileSOURCE=$(TMP)\testfile.cpp# End Source File
Open Visual C++ .NET. On the File menu, click Open Solution, and then click All Project Files on the Files of type list.
Browse to the folder that contains the modified .dsp file, and then open the file.
When you receive the prompt, Do you want to convert?, click Yes. An error is generated.
