I am trying to run an MSP silently and also without rebooting. I have:
msiexec /p "mypatch.msp" /s/v/qn
which basically means run the patch silently / no interaction. The /v I believe is supposed to be the switch to send the 'qn' parameters directly to msiexec. So, in order to tell msiexec to not restart, I would think that saying '/v/norestart' would work, however it does not (the command ends up being invalid and I get the msiexec usage/help dialog)
Is there a way to send multiple parameters to msiexec when installing a patch?
