Hi, just to drop a note, in case someone has similar issues:
I had considerable problems with the precompiled windows host msvc binaries. Linking to the debug lib file caused linker errors, and the release build wouldn't discover my installed plugins.
Now I build everything from source and it works. I use visual studio 2005 on vista. This is just a hunch, but are the libs build with multibyte or unicode support?
