Lighting not rebuilding. SWARM: "Error: A 32 bit processes cannot access modules of a 64 bit process."

Thanks for the workaround. Unfortunately I get this error in the log now:

15:43:09: [Interface:OpenJob] Error: TestException
   bei NSwarm.FSwarmInterface.OpenJob(FGuid JobGuid) in d:\Perforce2\UE4-Releases\4.5\Engine\Source\Editor\SwarmInterface\DotNET\SwarmInterface.cs:Zeile 2007.

At least the message from the title is gone.
