osu! version: Stable 20240513.1 (latest)

are you trying to open an .exe in notepad?

no. i tried opening it normally but i couldnt open osu no matter what i did. i figured that i could find the problem if i looked into the notepad.

Does osu! show any error? Otherwise follow wiki/Help_centre#event-viewer

I followed the link until it said to search for osu. osu did not appear despite having it installed.

Are you still experiencing this issue?

Where do you have osu! installed to and are you using the osu!.exe from that folder to open osu!?

i should have changed this forum. i found out its most likely because im using windows 11 pro and it doesnt support 16-bit.

osu! is a modern game, and 16-bit app is stuff from the MS-DOS age aka around 30 years before.

Can you open any other .exe file by double-clicking? What does \HKEY_CLASSES_ROOT\exefile\shell\open\command in the registry read?

i opened it but im not quite sure what you mean.

im experiencing it as well but its not only osu its roblox too but it doesnt even load up at all. or says osu is installed

This sounds like someone's been messing with windows stuff that they shouldn't be. You don't just randomly lose the ability to run exe files lol

ill be honest. I'm not sure if its even a osu! problem anymore. it might be because its a new pc and it costed around 300 dollars.
