kssonline04 On installing the Add-On in preferences in blender. Below message is showing , ' upgrade to 2.8x '. I dont understand which version is this. Also, Chordata submenu not showing under windows drop down menu .
daylanKifky You are probably using a version of blender previous to 2.80. You can tell by looking at the version number on the splash screen. There was a mayor update in blender at that version and many addons are not compatible with the previous ones.
