GRBL Panel 1.0.9.0 won't run on WinXP

When I run 1.0.9.0 on my XP laptop an error "... not a valid Win 32 application" comes up. It (1.0.9.0) seems to come up on my Win 7 -64 desktop. What are my options???

I am looking for panel software to drive an Arduino that will send G-Codes to the parallel port of a 3-axis TB-6560 Controller.

Is the Toshiba TB6560 'bypassed technology'?

Thanks,
