I do not believe that you need 1TB.

You probably shouldn't but I'm getting the same issue.

Yep, same here.

The unusually large size of the patch offline installer already suggested that GOG likely put it together in an improvised manner and with little to no testing at all.
I appreciate the effort to make it right, but... try again, GOG.

Yep, I got the same message as you did on the image.
I had to double check to see if there was a decimal point, but nope it was a 6 digit whole number.


I do applaud GOG for actually putting out the missing patch. It feels like this team is understaffed & pressed for time.
Hotfix #10 is already out, so they got to start working on that I guess.

With steam the patch4 was 14 gigs, and that somehow had people complaining about 2.5hr patching time, but some taking 30 mins. Its a mixed bag.

It looks like patch4 did some major file changes with "deleting" all the "patch#.pak" files & merging them all back into the main game files as they no longer exist after the patch & which also lowered the game install size.
