We are deploying a new server (Terminal Server - Windows Server 2008 R2) and one particular program will not run (it freezes up and goes not responding every time we try to start it up). The vendor is pretty sure that the cause of this problem is a corrupt Microsoft .Net 3.5 installation. He said in Windows Server 2008 R2 it is not as easy as it used to be to uninstall and the reinstall the .Net framework.
Does anyone know if this is possible and if so, does Microsoft have a knowledgebase article or some other kind of instructions for uninstalling and reinstalling the framework?
He's tried disabling and then re-enabling the .Net framework from the add/remove features option but that does not actually do a new, clean installation.
