RESOLUTION

Steps to Reproduce Case 1

1. In Visual C++ 4.0, create a workspace called Test of the Application type.
2. Insert a top-level project called Top of any type.
3. Using the Build|Configurations menu, remove the Test project and then close the project.
4. In Visual C++ 5.0, open the Test workspace's Test.mdp file. Visual C++ 5.0 converts the project. MSDEV crashes and the error messages noted above appear.

Resolution for Case 1

1. Under the Test directory which was created for the Test workspace there is a "Top" subdirectory. Rename this the "Top" subdirectory to "x" (any name is acceptable).
2. In Visual C++ 5.0, open the Test workspace's Test.mdp file. Visual C++ 5.0 converts the project.
3. Rename the "x" subdirectory to the original name and the project will work as expected.

In the general case, you may have several projects. Renaming any one of the subdirectories as shown above will work around this bug.

Steps to Reproduce Case 2

1. In Visual C++ 4.0, create a workspace called Test of the Application type. It should be located in the Test directory.
2. Insert a subproject of any type called Sub.
3. Close the workspace.
4. In the Test directory, rename Test.m?? to MyFile.*
5. Create a subdirectory called Test\Test.
6. In Visual C++ 5.0 open MyFile.mdp. MSDEV crashes and the error messages noted above appear.

Resolution of Case 2

1. Rename the Test\Test subdirectory to Test\[anything].
2. Convert the project using Visual C++ 5.0. Now you can restore the subdirectory name to Test\Test.

Please note that for case 2 the upper-level directory name is of no consequence. What is important is that there is a subdirectory with the same name as the original project name.

These scenarios apply to all versions of Visual C++ 4.x.
