Invalid drive when reinstalling launcher

So I ran into this classic problem, when trying to install UE4 on a PC that had it installed before.

I get "Invalid Drive: E:" when running “UnrealEngineInstaller-1.7.0-2282482.msi”

I dont have the E:\ drive on my computer anymore

I dont have a C:\ProgramData\Epic folder

I dont have any C:\USER\currectuser\Appdata\Local\Unreal* folders

I am admin on the PC

What do I need to fix before I can reinstall the launcher again?

Thanks!

Nevermind, I bit the bullet and reinstalled a fresh win 7. It was due after 2 years anyway. Problem solved.
