Yes, it's possible, but it requires quite a bit of code for those changes, which defeats the purpose of being a simple installer.

But I'll include that in the next update.

Can you enable Pause button by default in the next update? I just needed to pause a big setup because i had to do another job which require alot of resources and i observed the button is grey out. Since the button is already there, please consider to enable it. Thank you for your work. I use your script for my personal old games repacks.

Find PauseButton.Enabled := False; in the script and change it to PauseButton.Enabled := True;
