Hello folks,

Was missing the dll when trying to launch the game (error message from the exe file, when I tried from galaxy nothing happened).
Found a missing update for my win7_x64 there :
https://www.catalog.update.microsoft.com/Search.aspx?q=KB4019990


Everything seems ok now.

I can add to this:

I had the same error, downloaded the manual installer but when I tried to install it would just loop at "Checking for updates" and never install.

The solution to this was to set my Windows Update preferences to "Never check for updates" and restart the PC.
After that I could install the manual update and finally run the game.
