Usually it's a good idea to install on the default path if you are not a exsperienced user. If you have not used the default paths to install the applications, then that might be your issue. But i can't tell.
Usually you can change the install paths for the plug-ins as long as you don't move them afterwards.
I presume you have not selected any Banks, or have new banks.
It work here with Jupiter 8 too.
EDIT: BTW. Have you opened in the standalone application before in the plug-in? It should'nt matter for Arturia applications, it don't here, but just in case.
