How to create a OuterNotebook/welcome page in the Inno Setup uninstaller? - inno-setup

Question

I am using this code from the answer by Martin Prikryl to Custom Inno Setup Uninstall page (not MsgBox).
How to modify the first page of this code to show a "Welcome"-like page on the OuterNotebook page (i.e. without the MainPanel header)?

Answer 1

You create the page as any other, except that its parent will be the UninstallProgressForm.OuterNotebook, not the .InnerNotebook.
Tricky part is not how to create the page, but how to implement the Next/Back buttons.
The Next button on the "welcome" page must change the page of the OuterNotebook from the "welcome" page to the UninstallProgressForm.InnerPage. And of course make sure the active page on the .InnerNotebook is the first normal/inner page.
Conversely, the Back button on the first normal/inner page must change the page of the OuterNotebook from the UninstallProgressForm.InnerPage to the "welcome" page.
So modifying my answer to the Custom Inno Setup Uninstall page (not MsgBox) to cater for the above, you will get:

Note that there's no way to use the built-in images from the installer in the uninstaller. In my simple code above, I install the "welcome" page image to the {app} and load it from there.
