UE4Game-Win64-Shipping.exe

Hi everyone,
i encountered a really strange error with one of my italian testers for my project…

everytime i package my project (shipping) it works like a charm on my two test systems but everytime i sent away a new version to this tester he gets this error messge:

Basically it means that the UE4Game-Win64-Shipping.exe wasn´t found or that the location its supposed to be at (E:/) isn´t accessible… but here is the strange part… the project starts anyway if you cancel the error window and than runs perfectly normal… AND the system never had an directory E:

Within the project at Engine\Binaries\Win64\ there is an UE4Game-Win64-Shipping.exe but its located on C:… at that doesn´t seem to matter anyway :frowning:

The Project runs, but thats not a problem i am Comfortable leaving in as anyone can probably relate ^^"

It would be awesome if someone could help me with this, i have more or less sporadically access to the system through teamviewer if “more” detailed information is needed

Of course the error had to occur on a system that runs in a language that i barely understand and not on a german or english one…^^"
