I agree with @Age Management, don't upgrade from XP to Win 7. Much better to just buy new Win 7 boxes. The old computers can be sold - I sold mine to employees at fire sale prices ($50 with monitor, they were probably worth $100 at least). The employees appreciated the deal - I didn't push it on them - when they heard I was getting new computers they begged for the old ones. Your computers probably worth more than my 8 year old pentium 4 boxes.
@HMWLCMD, just to echo what has been said many times, the problem is not your hardware, it is Version 6 and crystal reports. If I weren't trying to go for the Meaningful use in 2011, I would have just stayed with version 5.
