Bug2: installer asks if to quit, you select "No" the installer quits (this)

BUG 1: This has always been the case, since the days when Yener90 created the code.
The same happens when an installation error occurs (IsDone Error).
What do you suggest? Should I close the installer by skipping the Finish page?

BUG 2: Since IsDone cannot resume the installation after canceling, it displays the cancel installation message, but since the return was already IsDoneError = TRUE, even clicking on cancel will exit the installation.
Maybe some change is needed to not display that last message.

If you have any suggestions for improvement, please comment. It is just not possible to resume the installation after clicking Cancel".
