I decided to try out the beta and put it on my sons computer since he was needing a format anyway. It is an AMD 64 bit processor with a Seafate 75 gig IDE 2 gigs of ram and an ATI 1950pro. Ran Vista fine. Anyway, I did a reformat of a the hard drive and all goes well it copys files and then gets to expanding files and hangs at 0% for about 3 mins then tells me that window was unable to install the files and that nothing was installed and I have to reboot to get off that screen. It has done it 10 times now so I know this isn't user error. Anyone have any idea? The DVD seems to have no issues as it got that far and it was validated and fixed when it was finished burning. Help please!!
