I have Enterprise 64 bits, I downloaded UE4 when it became free and I’m having trouble running it.
As soon as I click “Launch” the error “Unreal Engine has stopped working” comes up. It says the module with errors is called MSVCR120.dll. I downloaded the C++ redistributables from here and installed the x64 and x86 versions but none of them fixed the problem. I also had the same problem running the tech demos like the realistic rendered room.
Yes, that’s the information I was looking for. The Operating System line doesn’t show the Service Pack 1 (for reference, that line from my dxdiag information is Operating System: Professional 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.130828-1532)). You can get Service Pack 1 here. Try installing SP1 and see if that helps with this issue.
