Some non-MailEnable IIS applications (e.g. control panel applications) do not yet support native Windows 64 bit. As such, IIS (on Windows 64 bit installations) needs to be configured to run in 32 bit mode.
If the server is configured to run IIS in 32 bit mode, it is important that ASP.NET is also configured to run in 32 bit mode.

4. Form the Windows command prompt, type meinstaller.exe and press Enter.
From the menu presented, selection Option 13. Reset IIS Virtual Directory Configuration settings for ASP/ASPX platform.
When prompted to select the version of ASP.NET, select v1.1.4322 and then Apply.
Once the application has completed processing, select OK and close the MEInstaller application.
5. From the Windows Command Prompt type iisreset and select OK.
