So, project needs vive headset + unity.
Set up done, unity project made, set up, plug the two, start tweaking, fixing stuff... Aaaaand need to tweak the script. Double click, MS studio comes up... Need to reactive the license...
I don't have a personal license (and I never will get one either, given how many times microshit has been a major pain in my glorious ass, I tend to avoid their shithole of products at all costs. Somebody else actually gave me access for this project.
So, that doesn't work, goes to download a free version, aaaaaaand apparently my level of access doesn't allow me to install this one.

... UrghhhhhAAAAAAAAAAAAAAAAAAA

Notepad++ it is. 😶
