Careful with that Hyperlink (on your MSI dialog)

One of the new features in version 5 of the Windows Installer runtime is support for hyperlink controls on setup dialogs. Remember that MSI 5 is only available on Windows 7 and Windows Server 2008 R2, but there's no redistributable for down-level platforms.

In most cases when introducing new features, the MSI team made sure they don't break your setup on older runtime versions. For instance, older MSI versions simply ignore new tables that they can't use. This enables developers to create a setup that will run with basic functionality on older platforms but on the latest MSI version the new features would "light up".

The hyperlink control is different, maybe because it's not a table but a new control type in an existing table, the Control table. Thus, it causes your setup to fail on Windows Installer versions prior to MSI 5.
