How can I send a product's CD key during a Windows Installer installation?

A. Usually, when you use Windows Installer to install a program, you must still enter the product ID; however, you can send this information with the MSIEXEC command:

msiexec /a \[msi file\] PIDKEY="\[CD key\]"

Optionally, you can supply USERNAME=\[user name\], COMPANYNAME=\[company name\], USERINITIALS=\[user initials\].
