Thanks! I'm getting a crash when launching UE4 4.11.1 with it installed though.

(through marketplace)
Fatal error: [File:D:\BuildFarm\buildmachine_++Portal+Main\RocketSync\HostProject\Plugins\Substance\Source\SubstanceCore\Private\SubstanceCoreModule.cpp] [Line: 90]
Unable to load Substance Library.
I accidently installed this UE build to C:\Program Files (x86)\Epic Games\4.11 instead of the normal 64 bit path (C:\Program Files\Epic Games\4.11 or something), could this have something to do with it?
