I've installed the RTM Vista and it runs ok on my iMac core duo. However, when I try to activate Vista, it fails with error code 0x8007232B. The extra info just says "DNS name does not exist." All other networking works fine. (Well, except for trying to install the Novell Netware client. But that's a whole other story, for another thread, when I get around to it.) I had no problem activating the RC2 installation previous to this. I did a new install, not an upgrade. This is with an Enterprise license. Build 1970 of Parallels.
Ok, I guess it's another big "Never Mind" on this one. I just asked a co-worker who installed Vista on his HP 7600 to Activate and he got the same error. I love it when my Parallels machine works as well (or better) than a native Intel box.
