Windows 10: What do you mean it can't be "associated with this file type"?

I installed an old version of notepad due to the new notepad included with windows 11 being hot garbage. When I try to set it as my default app for opening .lua files, it refuses to do so spurting out the following error: "The programme you have selected cannot be associated with this file type. Please choose another programme"Is there any way to stop this? I'm practically pulling my hair out over this.

Restore Default File Type Associations in Windows 10  


Not to pester you, but it is inconvenient to "open with" every single time, and I remain quite perplexed why every other possible file extension appears to be listed in "Settings/System/Default apps/CHOOSE DEFAULT APPS BY FILE TYPE" but not .zip. It has always been possible prior to Windows 10 to associate ANY file extension with a default program. I'm not sure what you mean by ".zip is not listed by default." How else would one permanently associate a program with a file extension? The link I gave you, provided again below, as well as others I could find - indicates that that other people have .zip listed in their file type listings. Have you checked your listings available at location I've specified above? I have ... .yps, .z, .z96... and no .zip. Do you not see a .zip extension either but see essentially all others?
