Can you run two versions of stickies on your computer?

I have two laptops, Win10 and Win11. The Stickies 9 (latest version) works perfectly on Win10, but the 10.xx seems to be messed up on Win11. I was wondering if V.9 works on Win11, and if I could possibly put both on my Win11 computer so I would have access to the backups from v.9.

V10 runs fine on win11 but i had to install some updates as indicated by the stickies support forum:

What problem did you have?
