I tried to install the game but at the last second it fails and says "your copy of the game is courrpted" is it the game or the installer, is there anything that can be done?

Edit: I hust installed a differnt game with no issue, i think the seprate launcher is the problem but i could be wrong.

Edit2: problem sovled must have been an update

I'm getting this issue and it is a real pain.

When I install to a non-C drive storage device, I get this error, restart GOG Galaxy, then it reinstalls but now it is installing onto the C drive and with no error.

Going to try and let it install onto the C drive now and then transfer everything over to the non-C drive after.
