The AD Administrative Center executable is now working with Windows 7 64 bit. It needs .NET Framework. I recaptured the application.
1. On a clean CnB Windows 7 32-bit machine, I turned off .NET Framework 3.5.1 in Windows Features.
2. Prescan
3. Turn on .NET Framework 3.5.1 in Windows Features.
4. Install RSAT and turn on the components of RSAT in Windows Features.
5. Postscan
6. Build
