What release are you talking about? 8.02 or the latest nightly?
The nightlies don't have a compiler, nor an installer.
8.02 is the last official/"stable" release and the link you posted has the answer....
Search the forum, there are million+ threads about the vista/7/mingw problem.
This is the second thread I answer about this problem today
So
www admins, please post on the main page that the 8.02 release is not compatible with vista/7 and place the instructions how to get working compilerThis is the second time I ask for this. If there is no person having time to do it, please give me access, so I can do it!
