No, Bitcoin-qt doesn't work on Windows 7 at all.  That's why I'm running it along with a P2pool node running off the backend of Bitcoin-qt.  On Windows 7.  It works perfectly on Windows 8 and Windows 8.1.  It also works perfectly on Windows Vista. 


Before you start talking shite, try fixing your install, your internet, or whatever is wrong with YOUR installation, and not with anyone else's.
