got this at the start of the video and after OK it kills whole installer (in the folder remains only unistal.exe and gameux...dll) ... no idea what might cause it (tested various virtual drives, various states of clean windows 10 starts with pretty much all other programs closed, have enough HDD space and ram ,... )
Saw this problem in couple topics especially in ones with videos , but noone mentione solution to it there :-(
EDIT: i guess it was codec issue.. works fine now
