It is clear that these games are troublesome to get started on NON-9x systems, but it seems that they do very little to help their customers to run these games.
Aside repackaging the original (or patched) version with all their pro and cons... usually alongside issues on running on newer systems, nothing is done.
I've bought several games that I can't play at all while some others will run after "community patching".
So, while technically these games "can" run on later windows system (the dreaded Windows Xp/Vista/7 compatibility), GoG do nothing to help their customers to do so.
To make a long story short: I've payed for something that I can't use.
In a normal shop I'll get a refund or substitution, on GoG I'm left with nothing...
