"Can not create game process" , launcher starts but ETS2 won't, not as an Admin or normal user , either with or without Online Armor active.
Then I suddenly remembered I had first installed TruckerMP and after that when I went to update ETS2 to the latest version for TruckerMP, I decided to relocate ETS2 on a new harddisk with more empty space :')
So TruckerMP could not locate the ETS2 folder anymore.
It would be nice if TruckerMP can not find ETS2, to say that it can not locate the eurotrucks2.exe in directory X:\blabla\ETS2\, instead of telling me it can not create the process, which is kind of uninformative and made me search for my security programs blocking ETS2 or missing Windows updates.
