If you have numerous users and don't want to manually install on each workstation, our EXE-based installers offer all of the same silent options that you can get with MSI.
See:

Alternatively, if you prefer MSIs, we generally suggest that you run the EXE, which creates a temporary subfolder under %TEMP% and puts the MSI into that subfolder. You can grab it while the installer is running.
The Clarity Client Addin allows users to lauch tasks (if the task is setup that way) from within Revit for the project they are working in, check change requests, connect to a Clarity Server if you are using Clarity with Revit Server and send diagnostics if needed.
