Copy the .MSI to a location on the network which all PC’s can see
Start GROUP POLICY MANAGMENT CONSOLE and right click on the appropriate OU (or the domain root) and select CREATE A GPO IN THIS DOMAIN AND LINK IT HERE
Drill into COMPUTER CONFIGURATION, POLICIES, SOFTWARE SETTINGS
right click on SOFTWARE INSTALLATION and select NEW PACKAGE
point to the shared location of the .MSI file (GP only supports .MSI files, not .EXE)
I like to choose ADVANCED because I like to rename the policy to include the date, but you don’t have to
Either wait a few hours for the new GP to drip through your network or run GPUPDATE /FORCE
