READ ALL of response 1, especially ....
"See the Operating System requirements in the System Requirements or similar for the program. " !!
You may NOT be able to use the program at all for XP, or you may need to install SP3 updates for XP in XP.
"xp proffessional,verson 2002 with service pack 2"
ALL versions of XP are Version 2002, with no SP updates, or with SP1, or SP2, or SP3 updates integrated into it.
If your Pro is 64 bit, it will say 64 bit in the same place you got that info
(RIGHT click on My Computer - Properties)
Automatic Update DOES NOT install SP3 updates automatically !
If you need Vista or Windows 7 for the program, there may be a version for XP.
If not, you need to BUY and install Windows 7, but your computer should meet or exceed the minimum hardware requirements for Windows 7 (CPU speed, amount of ram, etc.) , otherwise your computer will run A LOT slower in Windows 7 than it does in XP.
Windows 7 is VERY different from XP.
If you don't "get" all that, tell us the name of the file you downloaded !
