Found out what is really happening.
Nightshade: And for an additional datapoint, if you install it through galaxy while not uninstalling the non-Galaxy version, the non-Galaxy version not only works, but continues to work after uninstalling Galaxy. So the latter must be adding something to the system as a whole rather than anything about the Galaxy version in specific.
GOG did NOT remove the Steam DRM.
( Redirected DRM Client Check )
The downloadable installer will play just fine, as long as GOG Galaxy is installed.
They are just using the Steam Client API's apparently.
No, GOG Galaxy did NOT have to be running in the background. Just installed.
The C++ RT Error is just the game aborting because it could not find ( Steam Client / GOG Galaxy ).
GOG does need to update the web page to show "Required for DRM : GOG Galaxy Installed"
