enterprise does not ask for a key to install, and dont ask for a key here you will get a boot in your arse lol
I found the link geobot posted. Downloading en x64 via uTorrent. So I could update Enterprise N 8 by using "setup.exe /auto:upgrade"
It's all good. About 30 min left to go doing over 750 kb/s. UPDATE: What a breeze. It was one long upgrading but worth it. Had to activate it again with KMS patch.
