So i have downloaded this extension, and when i install it pops up a window on the screen saying nothing and says its installed but nothing its working and if we restart the program goes missing like it wasnt even installed, i tried first on version 1.3 (beta the one im using), then 1.2.9 doesnt even recognize the extension wont even install it, and same with other versions, i used the 2.2.0 NxPA latest version, so would like to know if there is something else i should be doing that is required, cause the extension seems to be good and would like to use it.

v1.2.9 is a very old release that doesn’t support extensions, the current version is v1.2.37 and I would strongly recommend updating otherwise a lot of extensions (especially mine) might simply not work.

v1.3 beta however should’ve worked, did you have any luck with other extensions? If no extension works for you I’d recommend checking this thread as there were reported instances where Aseprite “loses” its configuration folder.
