Repair ASP.NET - Vista Ultimate

GDay All,

I have a problem with ASP.NET and an Autodesk Web App. This problem has
lead to the discovery of some corrupt files in my ASP.NET folder.

I have tried repairing the files by running dotnetfx.exe from Microsoft
but this simply informs me that .NET is installed by the system. Hence,
no repairing takes place.

How do I repair/replace the corrupted files?

running SFC /scannow did not fix the problem either.
