ASP .NET 2.0 is Reported Missing

Tuesday, August 14, 2007
Various applications may return a failure indicating that ASP .NET 2.0 is missing, even though it's installed. Systems Center Operations Manager 2007 (SCOM) is an example.

This failure occurs if you install Internet Information Services (IIS) after you have installed .NET Framework 2.0. If you install .NET Framework 2.0, then install IIS while selecting ASP .NET 2.0 as an optional component, the ASP .NET 2.0 extensions might not be registered correctly in the IIS metabase.

The solution for this is to go to the %SYSTEMDRIVE%\Windows\Microsoft.NET\Framework\v2.0.50727 folder and from a command prompt, run the command: aspnet_regiis.exe –i –enable
