Reply from IIS7: http error 500.21 internal server error handler pagehandlerfactory-integrated has a bad module ManagedPipelineHandler

I recently installed a Win7 win VS2010 and IIS7.  Unfortunately I installed VS2010 before IIS.

After some other bugs I got something in the line of

http error 500.21 internal server error handler pagehandlerfactory-integrated 
has a bad module ManagedPipelineHandler

The solution was to reinstalls Dotnet4 with IIS and that is done through aspnet_regiis.exe

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

or the version you use.

Here is the caveat: you have to run it from a prompt with raised privileges.  The output doesn’t give you any clue about this but just outputs its help instead.  Typically shift-right-click and start the command prompt as administrator.

    Thanks for the help. Have to always be cognitive of installing components without administrator permissions. Keep up the good work!

    Regards.
