Hello everyone, Im sorry if this has been posted before. But I´m having the infamous 0xc000007b whe I try to run the UE4 engine. Already tried reinstalling directx, microsoft visual c++ 2012 and 2013 and event went as far as downloading those dll packs that oppped up in every search I did. But still cant seem to get it to work.

I m using windows 7 with service pack 1. I installed DWalker and got a log file but cant seem to be able to uploade it here.

Any help is much appreciated since I´m really new to this.

Thank you
