Then, double-click on the file named PhysX-SystemSoftware_bak.msiĪccept the license agreement and then it should pop up with an error stating that 'The currently installed version of the drivers is newer than what you are trying to install'. (Replace C:\Program Files\Steam with the folder where you installed Steam) To do this, go to C:\Program Files\Steam\SteamApps\common\Dishonored\Binaries\R edist 'I just was able to fix msiexec always launching and trying to install due to the fact that the PhysX installed on my computer are newer than the version included with the game.įirst, make sure that PhysX is what is causing the problems.
SO I found a thread about MSIexec for Dishonored, it's about PhysX but folowing the instruction just made that the instal pop-up with msiexec don't show up anymore.
