Hi ndrakey,

re: Is there a way to get CustomUi to work on Windows 10?

It does work on Windows 10 already, but it needs the final release of MoI v3 in order to run. From your screenshot it looks like your problem does not have anything to do with Windows 10, it's that you're running an older release of MoI which doesn't have the getUIDir() function that the error message is referring to.
