Ever had the anoying error message “Could not complete command” when creating a new project? Or had the error that Visual Studio could not start the wizard 'CSharpAddClassWiz.vsz'! After reading some post about people who had the same problems and suggested a complete new install of the OS and Visual Studio i searched for a simpeler solution! In my case the command 'regsvr32 C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\vcpackages\csproj.dll' was enough to make everyting work correctly. It seemes like a third-party tool unregistred this .DLL when i uninstalled it.
