This content uses a simple example of alternate content with a clickable link. The user must click the link to proceed with the popup based installer. The popup installer is the frame-based installer page loaded into a popup. This can help circumvent issues with frames. It can also be triggered in many ways which circumvent popup blockers, because it is advised that only user interaction, such as a click, triggers the popup. The developer is in complete control as to how their users will install VMP.
