32 and 64 bit versions of Sandboxie

[atomicorion]

I'm ready to purchase the lifetime license of Sandboxie but not sure if I should get the 32 or 64 bit version?
Why I ask is because I currently have a 32bit windows 7 pc and am also in the process of building a 64 bit gaming pc.
If I purchase the 32 bit license now to run on the current pc,will it also work on the 64 bit windows pc later as well?
OR...Do I need to purchase a separate 64 bit license?
Thanks in advance

You receive a Product Key with your purchase, and it works with both the 32 and 64 bit versions.
And it can be used on all PC's that you personally own.
