Yesterday I reported something which looked very weird trying to setup the VS 2005 beta. Which even scared some other people. I found out what had happened. The dvd images available don't load in Virtula PC. So I burned a physical DVD. In the download dir was still the may preview as well and my burning software (or actually myself...) picked the wrong image. Indeed I installed the May preview again. Blush blush... I am really sorry for all the inconvience.
As an alternative I found a very simple virtual CD drive. This works under Virtual PC and right at this moment it is installing the real beta.
