Ya, that's right ! There are 4 Versions of the Windows Installer Runtime 1.0, 1.1, 1.2 and 2.0 !
But you can also make an "Upgrade Version" or and "Advanced Version" in the Download-Area, for those people how know they have the latest Version of the MSI Installer ! Like me for example !
PS: And I also know about the frustration and errors, because I'm a software developer !
