v36a is the last version, works fine in widows 10, (64bits if that matters) don't need for stuff like compatibility or anything
just install and run from the shortcut\programs
EDIT; i did read a second time and it appears you are having problems with the save manager part?
it works fine as well in my side,
i tried to save manager in my m3 sd card, works as intended :s
make sure you have the folders like gamesave in your sd card
