That is a good suggestion and I can do snapshots. Thank you for your response. I have Google'd this topic, but I cannot seem to find someone who has actually done this. Next week, I will most likely take a snapshot of our test environment first and try to uninstall and re-install the .NET framework there. If that goes well, I will try it on the production environment. Unless, someone else has done this before and is willing to share their experience, I will post my results here for others to see.
