In case you also have an AMD Graphics Card you might get an error "Software 3D: Error initializing Graphic Interface". Check if the problem is what the fix for is: - Go to "C:\Program Files (x86)\GOG Galaxy\Games\Settlers 4 Gold\Exe" - Make sure it is a problem with "minidumpwritedump" in "atiumdag.dll" by starting S4_Main.exe directly If an error message comes up multiple times mentioning "MiniDumpWriteDump" and / or "atiumdag.dll" continue to fix: - Go to "C:\Program Files (x86)\GOG Galaxy\Games\Settlers 4 Gold\Exe" - Locate a file called "DbgHelp.dll" and rename it to like "DbgHelpOld.dll" - any other name should do too. Now start the game again through GOG or directly. Explanation: It seems to me like the latest ATI Driver might want to use functionality the game developers should provide by todays standards - since the functionality seems to adress Debug-Standards what is usually only necessary for software development it seems safe to disable the whole file by renaming. This Error also seems to occur at other games / software.
