Visual Studio 2008 skipping projects when building a solution

[Pragadheesh]

Hi,

I recently installed VS2008 in Win2k8R2 machine and opened a VS2005 project(C++). After successful conversion to VS2008, i tried building the project in Debug x64 mode. But the project is getting skipped. I tried Clean as well as Rebuild, and it is getting skipped for those as well.

I'm able to build in Debug win32 mode. But i need to build in x64 mode.

Also the Build option is ticked in Build->Configuration Manager under x64.

I have installed the x64 bit compiler too.

Also I'm not able to see the Project properties for x64.

How can i solve this problem and build the project in VS 2008?
