So, I'm trying to get into Escape from Tarkov modding, which requires a sort of "Placeholder Server" for when you're testing your mods out. Thing is, that Server is made in something called "Node.js", whose latest version doesn't work with Win7. So I asked around, and I was told to add a System Environmental Variable on Windows called "NODE_SKIP_PLATFORM_CHECK=1" and it should all work fine.

My question is, will adding that variable change or break something? This is my first time ever doing any fiddling with Environmental Variables, so I'd like to know what I'm doing beforehand.
