Which version/SP of Windows are you running? Try unzipping and running (from a Command Prompt) the attached test program on each project. To determine the values to pass, open the .sln file in a text editor and extract the name and URL from the Project line:
For instance,
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "MyWebApp", "http://localhost/MyWebApp/MyWebApp.csproj", "{87215A73-B136-4ED2-9F93-1E16563ACD3F}"
would translate to
TestVirDir "http://localhost/MyWebApp/MyWebApp.csproj" "MyWebApp" > output.txt
Then post or send to
support@kinook.com the output file for each project. Thanks.
