hi,
just shortly i started this thread about Gem on Windows 10
[PD] how to get GEM working in Vanilla?
https://lists.puredata.info/pipermail/pd-list/2016-05/114954.html
no solution, yet.
the library is not loaded;
neither with Gem from deken nor from iem.
it looks like there are very few people working with Gem and Windows 10
(and reading this list).
