I'm trying to upgrade my SM15 instance to SM16 (latest) on windows server 2008 (not R2) 64bit and the install just sits on Configuring Windows Features for forever (I gave up after 20 minutes, extent of my downtime window). I tried again after restoring 15, same result.
I know the system requirements say 2008 R2, but not sure why it wouldn't run on non R2 64 bit, I have .net 4.6.2 installed and a bunch of other .net software runs just fine. I'm not in a position to upgrade the OS just yet, it will be a few months before we have a new server available. Has anyone else managed to install on 2008?
