Tippae1: I just get a windows error message stating HOMM 2 has stopped working . and then it closes. Any help from the community?
With so little to go on, probably not. There are 6 different releases of Windows you might be using (Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, or Windows 10), and all but one of them come in two architectures (32 bit and 64 bit). Since you set your location to "US" and your English seems good, we can probably assume you are using an American English version of Windows. Beyond that, we would be guessing.
Generally, for problems that lead to a game crash, you should contact GOG support. If you contact them soon enough after purchase, and after following their advice you still cannot get the game to work, then you may be able to get them to approve a refund. If you ask the community for help, and we cannot solve your problem, then you are stuck. You are welcome to seek community help in parallel to the official support channel, of course. See
https://www.gog.com/support/website_help/money_back_guarantee for details.
If you still want to pursue community assistance, please start by telling us what version of Windows you are using, what version of Heroes 2 you are trying to play, and any steps you have tried to solve the problem. Check that you are current on system updates. I have Heroes 2 Gold working fine here with minimal configuration.
