A classic and for all settlers fans and where it will not be ... it will bring you!
I use Windows 7 64 bit and have the Kompatiblitätspatch not needed, a Kompatiblitätseinstellung in exe.Datei in the Properties tab to "Windows XP (Service Pack 2)" was sufficient because this paid version has the latest patch (1.60) has included. Changing the resolution within the game is simple with the F3 key.
For the price and the content of all the addons Settlers III series recommended quite clearly.
