Hmmmm... This is a not just a case of "Not Supported", it blindly refuses to install! Yes, I've seen earlier versions (I don't think it was 6.5, maybe 2000 early betas or so) where you got that kind of message, but it would still install. "Just don't expect any support" what the real message should have been reading 😀

opc.three, thanks for the link you gave me. There is says under "Breadth Editions of SQL 2012" that it is supported on Windows 8 Professional 64 bit as well as Windows 8 64-bit, where the latter leads me to believe that it should work under Enterprise as well. Your thoughts?
