--- Comment #4 from Hans Leidekker hans@it.vu.nl 2007-11-04 13:00:20 --- I can confirm that Dan. With msttcorefonts installed the Windows corefonts installer succeeds but leaves nothing in c:\windows\fonts.
This is not strictly a Wine bug, so perhaps our wiki is a better place to document it?
Mono's dependency on corefonts is documented in other bugs. I think was it was introduced when they switched to libcairo.
