The following examples will allow you to perform the described actions.
To install OAC silently, with verbose logging, you must use the following command:
msiexec.exe /i "C:\< path to installer >\OdysseyAccessClient5.10.13456.0.msi" /l*v "c:\odyerr.log" /qn
If you wish to script a non-interactive upgrade from OAC 4.8 to OAC 5.X with verbose logging, you will need to use the following command as the silent switch will not work:
msiexec.exe /i "C:\< path to installer >\OdysseyAccessClient5.10.13465.0.msi" /l*v "c:\odyerr.log" /qb
To silently uninstall the application, you would need to use the following command:
uninst.exe /silent=1 /noreboot=1 _?=C:\Program Files\Juniper Networks\Odyssey Access Client
