"Completely" silent uninstall for Acrobat 5 on Windows XP

The script line for the command prompt or batch file is as follows:

C:\WINDOWS\ISUNINST.EXE -y -a -f"C:\Program Files\Common Files\Adobe\Acrobat 5.0\NT\Uninst.isu\" -c"C:\Program Files\Common Files\Adobe\Acrobat 5.0\NT\Uninst.dll
-y bypasses the first set of prompts
-a sets "no to all" when or if it encounters shared files
