Sygate Firewall??

About 7-yrs ago, my son built me a Win98 computer for my
birthday. I have been running Sygate Pro v5.5-2710 on it
with excellent results.
Today I found out that my son and daughter are building
up an XP computer for my birthday, again.

Does anyone know is Sygate Pro v5.5-2710 can be run
on an XP box?? If so, did you encounter any problems
with it??
Thank you,
