I have followed the instruction to install the YuniquePLM Adobe plugin to the letter yet its still not appearing in Illustrator
This just happened to me and though I would share. The main tool "Adobe Creative Cloud" application needs time to properly update. So after you installed the plugin. launch Adobe Creative Cloud, let it update, check for updates, wait (mine took over an hour) check for more updates and reboot. Only then did the plugin show up under Windows, extensions.
