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);

.

Thank you for your quick reply, but even with the edit's codes, I am still facing the same problem. Are there any problems for you with these codes in the script?
