The game cannot run, i get the "can't find Xapofx1_5.dll, nor X3DAudio1_7.dll

should I just download said *.dll's? or is there any other fix?

Hi guilletor, sorry to hear you're having problems.
It sounds like your DirectX installation is broken somehow. Unreal engine usually checks and updates DirectX, but there must be something wrong on your system. Try re-installing DirectX. https://support.microsoft.com/en-gb/help/179113/how-to-install-the-latest-versio...
