This is not FDK-related.
There IS a long thread in the adobe.atm.type.windows forum, with a
link to an article by Tom Phinney about similar problems.
For your convenience, here's the link - but I'd strongly suggest
reading that thread - many of the problems are related to Nvidea
drivers. The subject of the thread is "Unable to install Type 1 fonts
in Windows XP"
