Impossible to reinstall UE4, 'ghost' older version involved

Hi ! First, excuse me for my english.

I had UE4 installed on a drive I don’t have any more. Ever since, it’s impossible to reinstall it, I get this prompt each time I try :

I read a lot of topics about it, and no one had a satisfying solution to my case.

What I tried :

  1. Cleaning registry keys with CCleaner
  2. Searching manually into registry keys to delete every unreal or epic games related keys
  3. Using Microsoft Fix It

I’m running out of ideas and I’m quite reluctant to the idea of reinstalling windows…

Thanks for your help :slight_smile:
