The first bug is missing in "CIUv3 3.0.0.1.b9.u1 (2021.09.11)".

The second bug
It seems to be fixed with these changes.
Without using Diskspan, of course

function BrowseArcFile(const ArcFile, Disk: String; var SrcDir: String): String;
...........................
      IDCANCEL : begin
        Waiting := False;
        ISDoneCancel := 1;
        ISDoneError := True;
        ResumeProc;
        WizardForm.CancelButton.OnClick(nil);
      end;

Change to

      IDCANCEL : begin
        Waiting := False;
        ISDoneCancel := 1;
        ISDoneError := False;
        ResumeProc;
        ClickButton(@CancelBtnClick, nil);
      end;

It is better to be like ASIS so that the installation process can be canceled by clicking Cancel.

When I mentioned "any suggestions", I was referring to the behavior of the action when clicking the cancel button, or whether it should display the exit message.
You didn't necessarily need to have informed what changes need to be made.
But anyway, thank you very much!
I will review in a few days. I'm out of time at the moment.

Thanks for reporting so bugs.
