Your choice. I know several OSs that won't load in VPC but will in the other free virtual machines so I thought it might be worth a try. What have you got to lose (other than your frustration)?
I think its my luck with Windows betas. I know to get Longhorn 3706 to work, I have to set my computer date to October 29th, 2002. My VPC BIOS always resets it's CMOS memory back to the real date.
