UnrealLightmass.exe unable to start (0xc0000142)

Not sure if i should post this here or Using UE4, but this error is a problem. Out of nowhere, I can no longer build my lighting. From what i know (0xc0000142) should be a .dll error, i think… tryied reinstalling VC++ but no fix. Any suggestions?

Recently had a system crash after a windows update which corrupted one of my projects, could be behind this error.

Found the solution. I had to uninstall then reinstall the whole launcher.
