If you want to solve your issue I suggest you tell exactly what kind of error you receive (perhaps in a new thread) and send a ticket to support.
I know it's a pity we can't have all our games work just like that but sometimes you might need to do something that your particular setup (hardware, OS etc..) requires.
If it's the first game, it seems to be wise to try that 1.7 unofficial update.
Thanks but I have posted it already but noone had answered it. I tried the 1.7 but it doesnt work (I had to put off my anti virus program because it saw the patch as a tojan virus.
Hercules, it is extremely frustrating regardless. I have created a post detailing my particular problem and I have requested assistance to GOG's support department. I have yet to hear anything. Right now it feels like I purchased a defective product.
I also have that feeling.
