This is the information I got from a Dev at the PlayOnMac site.
------------------------------------------------------------------------------
For any large enough GOG installer (the ones that take more than 9 minutes to install, or something like that), you'll probably run into bug #32451 https://bugs.winehq.org/show_bug.cgi?id=32451
Workaround is to supply the installer with a /nogui parameter, but that cannot be done thru manual installation, only scripting.

Seems us GoG game owners need a script written to run their version in a wrapper

I know he states the 9min marker but it does not take that long before it errors, I did give him all the error details so I have to trust
he knows the problem from the information given on the error received.
