The desktop shorcut works completely fine, and the application seems to be functional too. However, when I use the taskbar shortcut, it displays Error 16. I'm also sure that the permissions are set for SLStore, although there is no Adobe PCD. The individual permissions for SLStore may be different though, as the instructions Adobe gave only gave a few on the list.
If you start from the desktop icon do you get a second taskbar icon?
Yes, but now it suddenly seems to be working. I don't know what happened.
It seems that if you pin it from the desktop shortcut and not from the open application it is functional.
