trouble installing Python-2.2a1.exe

[Tom Good]

I downloaded the Python-2.2a1.exe installer from SourceForge, and
verified that the MD5 sum is correct.  When I run it under Windows
2000 Professional [Version 5.00.2195], I get an error dialog that
says:

16 bit Windows Subsystem

The NTVDM CPU has encountered an illegal instruction.

application.


Any ideas?
