I work for De Montfort University and support the Game Art course here. We have over 200 students using Unreal Engine within a restricted user (non-admin) environment - it would be carnage otherwise! I have notice during packaging that Unreal immediately errors due to a requirement to write to C:\Program Files\Epic Games\UE_4.16\Engine\Intermediate\Build\XMLConfigCache.bin
I know our situation is not exactly typical to industry use, however, we still represent a significant number of users and I wondered if Epic might consider modifying their paths to automatically accommodate restricted users? I don’t believe the problem existed in 4.13 and I am hoping my testing with 4.18 might bare fruit.
In addition to this, though this is restricted user related rather than packaging, it is a particularly big headache to have to deal with a constantly updating Launcher which partially runs but ultimately breaks the link between the Launcher and the Engine. Could there be some consideration for the restricted user environment in respect of this problem? Ideally a deployment tool and the ability to switch off automatic updates of everything.
Edit - 4.18 still requires write access to restricted areas unfortunately.
