The game runs properly right away however it's missing all the pop up hint on mouse overs. This is a complex game and the way the UI works make it a bit harder to navigate even if you can do without.

There are also problems with drag and drop like if you try to move the map legend around it's quite buggy.

Is there a way to fix it myself? I assume the pops are missing because it relied on some old windows API, I've tried compatibility modes to no avail. Is there some tool out there that can substitute for it like some tools do for old direct X calls?

Tooltips are now properly displayed in game for some reason, I don't think I changed anything.
