How do I check if Windows Installer 3.1 or higher is installed?

I need to know this since this is a pre-req for .NET 3.5 and if I'm including the .NET bootstrapper, I should also see if Windows Installer 3.1 is needed.

Right now I'm checking for the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows XP\SP3\KB893803v2

Which will check for Windows Installer 3.1 but I suspect it doesn't check for higher versions. (Haven't been able to confirm or deny that)

What registry key should I look at to find this information?

Edit: I need to check this in Inno Setup which is what I'm using as my bootstrapper, and I'm not sure how to check a dll version in there.

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.

Right click on MSI.DLL , select properties -> go to Details tab and check file version.

On the "Run" window, type "msiexec". A window will come up showing the Windows Installer version on the first line.

locate the installer msi.dll with this registry path: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Installer

value: InstallerLocation

then get the version information from that file.

update: the way above is old! new way to detect the version is documented here: http://msdn.microsoft.com/en-us/library/aa368280%28VS.85%29.aspx

If this is inside the MSI file itself, you can check for the VersionMsi property.
