The deployment module is associated with each of the users, since it is installed in C:\users\<current profile>\RDP6.
Deploy a logon script that will install Setup-ConnectionClient.exe in silent mode: 'Setup-ConnectionClient.exe /VERYSILENT'
We do not provide any .msi file, but you can generate an MSI from Setup-ConnectionClient.exe via "EXE to MSI Converter" for example.
You can also configure a .bat file that will run every time you log in, and that will launch this command line: 'Setup-ConnectionClient.exe /VERYSILENT'
Doing this, the connection module will be installed in a completely transparent way.
However it is not possible to install in machine level, because Setup-ConnectionClient.exe installs files in the 'RDP6' directory of the local session.
