So I am trying to run a quite installation, with my msi, and it seems like I can easily pass a number for a parameter that I have, but I can\'t seem to pass in a string...I
If you invoke from Powershell, you should use the call operator & This should then also work with parameters enclosed in quotes:
& msiexec /i `"My Installer.msi`" /quiet JREPATH=`"c:\BLA BLA`"
