Won't Install Font - Similar Installed

A client issued a new style guide, switching ALL fonts to Google font Muli. MainType won’t let me install Muli Italic, Light, or Light Italic, though, because it says a similar font is already installed. The client won’t allow a similar font - they only want Muli. Is there a way to override this issue?

Thank you.

I downloaded the fonts from 1001 Fonts and installed them without issues.

Do a Quick Search in MainType for “muli” and see if you already installed it earlier. If it is already installed you would get that error message.
