@ADMIRAL,

after making a few changes to the code, you can make it work. however, if i'm correct, there're some aspects in the script that need further implementation. it would be better to ask the authors to complete the script.

Edit1: 

* Replace the current 'ListBoxOnChange' code with this.

procedure ListBoxOnChange(Sender: TObject);
var
  ADir: String;
begin
  if (FMXListBox[2].GetItemIndex > -1) then
  begin
    ADir := FMXEdit[1].GetText;
    StringChange(ADir, ExtractFileDrive(ADir), FMXListBox[2].GetItemText(FMXListBox[2].GetItemIndex));
    FMXLabel[197].Text(MinimizePathName(ADir, WizardForm.DirEdit.Font, WizardForm.DirEdit.Width));
    FMXEdit[1].Text(MinimizePathName(ADir, WizardForm.DirEdit.Font, WizardForm.DirEdit.Width));
    WizardForm.DirEdit.Text:= ADir;

    FMXDiskUsage.SetDir(WizardForm.DirEdit.Text);
    FMXLabel[82].Text(MbOrTb(FMXDiskUsage.FreeSpace, 1));
    FMXLabel[85].Text(MbOrTb(FMXDiskUsage.FreeSpace, 1) + ' is available from the selected drive');
    FMXArc[5].Angle(FMXDiskUsage.FreeSpace, FMXDiskUsage.TotalSpace);
  end;
end;

procedure ListBx3OnChange(Sender: TObject);
var
  ADir: WideString;
begin
  if FMXListBox[3].GetItemIndex > -1 then
  begin
    ADir:= ExtractFileDrive(FMXEdit[1].GetText) + '\' + AddBackslash(FMXListBox[3].GetItemText(FMXListBox[3].GetItemIndex)) + '{#MyAppName}';
    FMXLabel[197].Text(MinimizePathName(ADir, WizardForm.DirEdit.Font, WizardForm.DirEdit.Width));
    FMXEdit[1].Text(MinimizePathName(ADir, WizardForm.DirEdit.Font, WizardForm.DirEdit.Width));
    WizardForm.DirEdit.Text:= ADir;

    FMXDiskUsage.SetDir(WizardForm.DirEdit.Text);
    FMXLabel[82].Text(MbOrTb(FMXDiskUsage.FreeSpace, 1));
    FMXLabel[85].Text(MbOrTb(FMXDiskUsage.FreeSpace, 1) + ' is available from the selected drive');
    FMXArc[5].Angle(FMXDiskUsage.FreeSpace, FMXDiskUsage.TotalSpace);
  end;
end;

Edit2: 

* Comment out the following line in the code.

//FMXEdit[1].OnChange(@ListBoxOnChange);

Edit3: 

* Replace the ListBoxOnChange event with ListBx3OnChange for the FMXListBox[3].

FMXListBox[3].OnChange(@ListBx3OnChange);
