I've been given an XP SP3 laptop to work with that seems to have corrupted .Net frameworks. 2.0, 3.0 and 4.0 appear in the Registry under NET Framework Setup, and under C:\WINDOWS\Microsoft.NET\Framework but no .net frameworks appear in Control Panel\AddRemove Programs, and Visual Studio can't open solutions.
I'd like to unintall 2.0, 3.0 and 4.0 and reinstall (at least through 3.5) but can't uninstall them since they don't appear in AddRemove Programs. I tried NetFxRepairTool.exe, but while it repaired the 2.0, 3.0 and 4.0 installations it identified, nothing changed with regard to AddRemove Programs.
Does anyone know what can be done here?
