Cura 4.12 won't let me associate the app with .stl files. If I dig into my PC settings I can find where Cura is associated with file type .stl.4.12, but not .stl.
I'm running a PC laptop with Windows 11 home 64 bit. I have uninstalled and reinstalled Cura using a newly downloaded install file. I do see that Cura seems to automatically associate with file type .gcode though.
Please help?
