I need help from you to merge two scripts found here to have preview image on a maximized components windows:
Just copy both codes and merge the InitializeWizard implementations according to this guide:
Merging event function (InitializeWizard) implementations from different sources.
Though, actually, the InitializeWizard in the Larger “Select Components” page in Inno Setup is noop. You can skip that. And you do not need to merge anything.
The only other change you need to do, is not to enlarge the ComponentsList in the LoadComponentsPage.
