Windows 7 x64, silent msi switch


Recommended Posts

I have a few MSI installers that I'm trying to batch to run silently, and the silent switch aren't working in both Windows 7 RC and RTM 64-bit.

I'm trying 7-Zip 64-bit.

This shows nothing, but does nothing either.

msiexec /i 7z465-x64.msi /qn

This shows the installer progress, but is fully unattended.

msiexec /i 7z465-x64.msi /qr

This happens with almost all of the MSIs I've tried it on. Am I alone here?

Only thing I can suggest without knowing more is to recommend that you use the /log switch.

Consult the Windows ® Installer SDK for additional documentation on the
command line syntax.

Next suggestion would be to launch task manager, click on the Processes tab, click on the Image Name column to sort the processes in alphabetical order. Look for msiexec if it exists and then launch your batch file and monitor for the start and finish of the msiexec process.

FYI, likely you know this but if not the /qn switch will not the UI at all.

And last suggestion would be to install the msi using the /qn switch on a computer where the application has not been installed before just in case the install is truly having issues.
