Cant Install FiveM

I run the fivem install as administer it opens starts install then closes and pops open saying how do you want to open this, anyone know a fix for this

FiveM does not run with elevated (administrator) privileges; make sure you are starting it in normal mode.

Tried this get same problem starts installing stops and says how do you want to open this file? search app store for apps, always use this app to open .exe

That’s quite interesting - it’s an .exe file and Windows knows how to open them by default. Something’s probably very wrong with your OS installation so you’ll need to troubleshoot that before continuing - I cant help in detail, though
