Install Word and Outlook plugins for all users in Citrix environment

Hello,

I am trying to install the Grammarly plugin on a Citrix server for all users.
This is a Word and Outlook plugin (grammar and spell checker).
The plugin will only install in admin mode but will not install for all users.

The plugin will install itself in

C:\Users\%username%\AppData\Local\\Grammarly\Grammarly for Microsoft Office Suite 

Select allOpen in new window

of the admin user account. The .DLL used in Word is the following:

C:\Users\%username%\AppData\Local\Grammarly\Grammarly for Microsoft Office Suite\6.6.116\09D34098D5\GrammarlyShim32.dll

Select allOpen in new window

I tried to copy this directory to the same location of a user account.
Then I open word and try to add the .DLL as an addin, but it doesn't work.
No error message, the addin/DLL will just not appear in the list.

I am not an expert with Office plugins, I would like to know if there is a way to activate the plugin for the standard users ?
