Problem opening existing Project is VS2008 on Windows 7 RTM x64

Question

When I attempt to open a project in Visual Studio 2008 Professional on Windows 7 RTM x64 that was created on XP I get the following error in Visual Studio error:

System.Runtime.InteropServices.ComException

All updates to Windows 7 and Visual Studio 2008 are installed.

Ideas anyone????

Answer 1

Same Problem here ! up up up
I thought I found the answer here: http://geekswithblogs.net/marocanu2001/archive/2008/05/20/annoying-visual-studio-2008-little-bug.aspx
But after adding the IIS Compatibility Roles to my IIS, I still have the same problem.


Update: it seems to be because it is a web application (C# in my case) and VS is trying to access directly the virtual directory declared in the solution

Running Visual Studio as an administrator / elevated priviledges will give you more explicit error messages.

For me I discovered that .NET2 wasnt properly installed and that a VirtualDir was also missing for the project to open.

Hope this helps

Answer 2

Found the solution to the problem here.....

On my XP machine I opened the Project and set it to use the Visual Studio Development Web Server instead of the local IIS.

I then copied the project back to the Win 7 x64 machine and opened the project just fine.  All is well now!!!

Best of luck...
