So I can across this problem while trying to install my new Rift.
It says it can't connect to the servers just after i accept the EULA.
The log says something about no valid install destination on C: and I noticed that my C drive is a dynamic drive.
I read somewhere that Oculus drivers won't install on dynamic drives and thought I'd try to reformat my drive and change it back to a basic disk.
Just thought I'd let you know in case someone else has the same issues.
