I'd say it's a good and simple bot, but it gets stuck when making unstrung bows because it clicks them and goes to a menu to string bows instead of the regular fletching menu. Might want to look into fixing that.
in the beginning i had the same error, but then i went to the settings of runemate and went to compatibility
there i made it run in comp mode for windows 7 and always run as administrator
after that it worked just fine
