Prerequisite Check Custom Page with Abort Button

I'd like to insert a custom page that will display the results of some prerequisite checks (Windows version/sp level, I.E. version, MS Access version, etc.) and if any one of the checks fail then I just want to enable an Abort or Cancel button.

Can someone point me to some sample code?

Cheers,
Ross

You'd probably check some registry entries. Use InstallOptions to create a custom page.
