Change language settings of Acrobat DC Pro/Std through Command-Line

Hi there,

I work in an enterprise environment consisting of a few hundred workstations. I am looking for a way to enable the French language support on all our machines with Acrobat Professional / Standard DC. The manual way I have found to do this is from https://helpx.adobe.com/acrobat/kb/change-language-settings-of-acrobat.html

Change Acrobat default language:

Go to Control Panel >Programs and Features.
Select Acrobat and and click Change.
Choose Modify and click Next.
Click Languages
Click on the drop down against the languages that you want to install and select This feature will be installed on the local hard drive.
Click Install.
CTRL+Click on Acrobat. You will receive a pop-up with a drop down to choose the language from the list of installed languages.

I understand there is a way to setup your default installation using the customization wizard to open the AcroPro.msi to have all langauges installed by default.

However, what would you do for existing clients that are installed already. Is there a specific command-line that I can reference to install the French additional language (without having to re-install the whole application)?

Much appreciated if anyone could provide a solution,

Thanks!
