fred54321,
I bought a Dell XPS 430 System (Desktop) it has a 64Bit Vista Home Premium installed, and I found out by trial and error, that Alot of Software whether it is 32Bit or 64Bit actually work on my 64Bit OS, I do use quiet a bit of the 64Bit Software, but some I cannot find for the system, so I have to revert to 32Bit, The Real Only Big Difference between the two are that 64Bit OS were Designed to handle Six and Above Gigabytes of RAM, while 32Bits were designed to handle up to the Six, but average around 4GB of RAM, I have found that a few software's will flatly refuse to run on 64Bit, and I agree, I think all software publishers should have the option for the 64Bit software running side by side of the 32 Bit... Another thing when I received my Desktop, it had the x86 Program Files Folder in the hard drive, so it is set to run it too. All in All I have only found software that I can count on one hand that refuses to run 64Bit... Good Luck My Friend... Marine43
