I upgraded my windows 7 ultimate to Window 8 pro early this year. Got the RTM version tonight thru my MSDN subscription. I ran the install and it only offer me Files or Nothing. What happened to all my installation? I have many developer tools installed and I donot want to go through it again. Multiple version of SQL server, Visual studio, share point and other, that is very painful to reinstall them all. How can I upgrade to 8.1 without losing my APPS?
PLEASE HELP......
