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

Yes, this one ‘‘Error: A 32 bit processes cannot access modules of a 64 bit process’’ , what version of the framework UE4 need ? The UE3 give you an installation of the framework 4.0, so at least I know the version it use. Now I only have the 4.5 installed on my PC, without it, the SwarmAgent just crash.

-Tried the firewall, but no
-Tried the Framework cleanup tool and reinstalling Framework ver 4.5, this can be it, but no
-Tried to revert from my registry of 2012, because I used Ccleaner and I was thinking that this may have changed the registry of the framework, good try, but no
-Tried to reinstall wind… well, not now :X
-Tried to use the SwarmAgent from UE3 with some files replacement, this was a desperate try and of course it doesn’t work, of course I reinstalled UE4 after that
-I was thinking of talking about that problem when I was buying some food, because the cashier tell me why I look grumpy today, but hey ! I dont think that would have worked too :stuck_out_tongue:
