That path is about 40 characters long, that is really pushing it when you consider Unreal will add its own incredibly long pathnames to that. You must be just hitting the 260-character limit.
I wouldn’t put the source code under Program Files anyway, that’s confusing and causes security issues.
Just make a path like: E:\dev\UE_424 and use that.
Hey i had the same issues i tried what was said above me by: Batty_Austin, his solution worked for me i went to my user’s folder from my local disk which you find in This pc on file Explorer and i saved it to my user’s Account, just to shorten the name of the file path and it worked, thank you very much.
Im getting this error? what do i do?
