Cannot install on Win XP

I understand that Win XP is partially supported per 
https://miktex.org/kb/prerequisites  But I am not even able to install MiKTeX.  I got the following error when I executed basic-miktex-2.9.6219.exe

An error occurred:
  source file: Libraries\MiKTeX\Core\File\win\winFile.cpp
  source line: 488
  message: Permission denied: path="C:\Program Files\MiKTeX 2.9\miktex/bin/MiKTeX209-getopt.dll"
  info: path="C:\Program Files\MiKTeX 2.9\miktex/bin/MiKTeX209-getopt.dll"
