I recently updated my PC to windows 11 yesterday.

Now I am having trouble installing and opening the file

Is there any way to fix this?

Yes, it does work on Windows 11. Trouble installing is usually caused by already having Polytoria installed to your computer. Try to play a game, and see if it works.

yeah it worked on my laptop on win 11

you could try doing what the other guy said or delete polytoria files altogether & then reinstall

thanks
