JudasIscariot: I had 3 updates that required some Microsoft Visual C++ runtimes to be installed and most of them were set to wait for the user to input something and I did not see the "uninstall" option highlighted (these redistributables were for the two Thief games and System Shock 2). Instead both the "Repair" and "uninstall" radio buttons were left blank.
In any case can you let us know which redistributables were set with the "uninstall" option highlighted?
cogadh: The C++ runtimes on those two exact games and PhysX on Two Worlds. They were set to wait for user input, but they had no options greyed out and were defaulted to uninstall. This is on Win 10, in case that matters.
I also ran those updates on my Win 10 machine at work. You don't remember which redistributables? Because I noticed that the older ones (2006 and 2008) would sit there and wait for my input while some of the newer ones (2010 and up) would just do their thing automatically.
Now, please don't take my statements as doubting you or anything, just trying to get to the bottom of things here as best as possible.
Could I ask you a small favor? Could you uninstall those games and then run the Galaxy install for them again and keep an eye on those redistributables?
