There is nothing special at all about using the command line to deploy the PolicyPak Cloud Client. It will honor a silent install and will not require or request a reboot.

Examples of typical silent command lines to run are below:

• To install the PolicyPak Cloud Client quietly with no UI:

  msiexec /i "C:\Temp\PolicyPak Cloud Client for company name.msi" /qn

• To install the PolicyPak Cloud Client quietly with no UI and no restart:

  msiexec /i "C:\Temp\PolicyPak Cloud Client for company name.msi" /qn /norestart

• To install the PolicyPak Cloud Client quietly using JOINTOKEN with no UI and no restart:

  msiexec /i "C:\Temp\PolicyPak Cloud Client for company name.msi" JOINTOKEN="AXBCDeVXbieqP9WUWQwnYM=" /qn /norestart

Note: Replace JOINTOKEN="AXBCDeVXbieqP9WUWQwnYM=" with the relevant JOINTOKEN string for your environment. See this KB for more information on how to use JOINTOKEN: https://kb.policypak.com/kb/article/911-policypak-cloud-automatically-join-groups-with-jointoken/

You may also create a command file to run the install and collect logs. 

setlocal
set d=%DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%
set t=%time::=.% 
set t=%t: =%
set logfile="%d%_%t%.log"
msiexec /i %1 /norestart /quiet /lv*x %logfile%
