If users need access to multilingual user interfaces in Revit, you can include one or more language packs in a Revit deployment. For background information, see Language Packs for Revit.
To prepare a language pack for inclusion in a deployment
Example:
If Revit has already been installed on user systems, you can install language packs on target computers. To deploy language packs for multiple languages or multiple products, create a batch file to install a series of language packs on each computer.
If you want to use the same basic deployment for a set of users, but subsets of these users need different combinations of language packs, you can first create the basic deployment. Then modify the deployment (or use it as a template for a new deployment) to add the required language packs for each user subset. See Modify a Deployment.
