Create a Desktop Sync folder in the Alfresco Content Services repository path:
Upload the latest installer files for Windows and Mac clients to this location.
Note: Don't rename the files, otherwise the client upgrade won't work.
Once the installer files are uploaded, users receive a notification telling them that an update is available and a new installation file has been downloaded.
Users will have to restart Desktop Sync to apply the new installation file.
See Updating Desktop Sync for more information about how an update is applied.
