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

Question

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

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

Please check this link may help you as already works for me for Windows 7, hopefully may work for other versions of windows as well to check Windows Installer version.

Answer 5

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