Xipotec: Will Sacred 2 Gold edition work with Windows 10 requirements just say Windows xp, Vista, 7 and 8. nothing
about windows 10.
That means the game isn't officially supported on Windows 10.
I haven't tried it myself, but apparently the game does run on Windows 10 with the community patch you can find here

From reading the notes, sounds like Sacred 2 was a very buggy game on release and the patch addresses several of these bugs.
People on the Steam forums seem to have found some rather, how can I put it, mysterious ways of running the game on Windows 10 without the patch. One person mentioned starting the game 3 times, having it crash and freeze in the first two and then the game working on the third try. Some also mentioned getting the game to run but getting a lot of crashes later. It's unclear if these crashes are Windows 10 related or not.
Strictly speaking the game is unsupported on Windows 10.
Edit: for some reason the link isn't showing correctly. Anyway, you'll find the link to the community patch in the PCGamingWiki page for the game.
