Found this on Reddit: how can i relocate unreal engine to another drive ? : unrealengine (reddit.com)
Seem like the best solution to avoid uninstalling and reinstalling. Trying it now, I’ll update if it works!
Edit: I couldn’t get this to work. The Epic Games launcher seems determined to not change the UE path for anything. I even tried starting the install, killing the Epic Games launcher via task manager and then copying all the UE5 files into the install location instead of the in progress install folder. When I open the EG launcher it still wants to resume the install… I’m out of ideas at this point…
