MSIEXEC what is the difference between qn and quiet

Question

I want to make a silent installation of an MSI file.

What is the difference between /qn and /quiet as parameters to msiexec.exe?

Answer 1

There is no difference. /q(x) existed since the initial versions of MSI and /quiet was added later in MSI 3.0 (Presumably to make it easier to understand by users.)

Command-Line Options (All Versions)

Standard Installer Command-Line Options (MSI 3.0+)

/quiet

Note The equivalent Windows Installer Command-Line Option is /qn.
