Upgrade PI AF Client through the command line

When upgrading a previous PI AF Client install, it is not necessary to re-specify the PI AF Client arguments or features. The command you enter to perform the upgrade varies depending on whether you are upgrading a 32-bit or 64-bit installation.

For a 64-bit upgrade:

msiexec.exe /i AFClient_x64.msi REBOOT=Suppress ALLUSERS=1 /qn

For a 32-bit upgrade:

msiexec.exe /i AFClient_x86.msi REBOOT=Suppress ALLUSERS=1 /qn
