The script is a helper to avoid manually copying, backing up, and doing boring stuff, it looks for the registry key that should be there if you installed properly UE4. The issue is definetly not related to using something else than C, is I currently use “D” and that’s why it looks the registry for the folder. I can’t however debug all situations, nor look at other OS Languages.

You can try reinstalling UE4, that worked for some people, but then egain, if it is not working you can do it manually as instructed in the first post.

There is not much I can do unless someone with the problem like you is willing to debug the issue with the registry and work out a solution. I can’t fix what’s not broken.

Thank you for your reply
I will try this soon, but after buy 1To ssd because anymore memory on my C disk. Hope it works
And without your script how do you change the build settings ( production, high…) on the previous version we had to change the folder in the engine but with the GPU 4.21 unified setting i dont know. it work with the unreal build settings?
Thanks again…
