Check if Windows Installer 3.1 or higher is installed?

Question

How can I check if Windows Installer version 4.5 is installed on target machine using registry.

I need to use this info in my installer bootstrapper and quit installation if WI 4.5 is not already installed.

I've checked HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\InstallerLocation but no information about its version.

Please advice. Thanks!
