I have a Surface Pro X and after Microsoft rolled out a more inclusive support suit for x86 apps Acti/Blizz launced a WoW client for ARM processors. The current Curse client doesn't recognize this version of WoW and doesn't allow me to download addons. When I try to add the file directory manuly I get the error "This is an invaliad directory or unsupported game". I only play WoW Classic and the exe is named "WoWClassic-arm64". All the other files in the folder have the same names so I assume they would function the same as the normal WoW client.
It would make things much easier if the Curse client could recognize the WoW arm client.
