May 18, 2005 - My system notified me of the Micosoft Windows Installer 3.1 update. How can I get the automatic update to download through 'Automatic Updates' without having to go. C: WINDOWS system32 wuauclt.exe is: 5,4,3790,2182. XP PRO/SP2 with all updates besides the Windows Installer 3.1 v2 update.

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: HKEYLOCALMACHINE 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.
Windows Installer is Windows' resident software that is responsible for installing processes as well as updating and removing applications. Developers can use it to author a setup file that consists of a single installation package. Additionally, your files, folders, registry keys, and new accounts are also safer with this program installed on your PC, thanks to its MsiLockPermissionsEx feature. Windows Installer also has the ability to enumerate all components installed on the computer and obtain the key path to each component.
