How can I detect if Windows Installer is installed?

Question

I've figured out a way to tell which version of the .NET framework is installed by reading previous SO posts, but I've not found anything about the Windows Installer.

Is there a registry key or anything similar that I could verify that Windows Installer 3.01+ is installed?

Answer 1

You can just include the redistributable version of Windows Installer and not have to worry about it.

"If you want to check the version of the Windows Installer on your system, check the version of MSI.DLL in the Windows\System 32 folder"

Check the file version of %SYS32%\msi.dll. On XP, it's in c:\windows\system32.
