You should also do what I say in #2 here:
https://www.vistastylebuilder.com/forum/index.php?topic=2430.msg13974#msg13974These xml files (classmap etc.) contain a lot of changes necessary to properly edit rs2,3,4 & 5 msstyles.
They aren't in the Beta by default because Panda X never got around to it so MrGrim did it himself and you have to add it manually.
It's the 8.1 folder because a 10 folder never got added.
Hi 3am, are those files in that post you linked still up to date? I already downloaded the beta and that 8.1 folder u referred in your post here. Do I need to change anything else in order to work with the program on current win 10 versions?
