Someone else posted this week about the same problem (though from a 
different cause) and solution.

Open Windows help, search 'environmental variable' and it should offer

That is not a Python setting. If you use any of the IBM utility programs 
that use the old Python2.2 and tcl/tk installation, and if any such 
program requires the TCL_LIBRARY setting (which it really ought not to, 
since a proper Python installation does not, at least not now), then you 
will have to work around the conflict with .bat files. But I would first 
write down the current setting before deleting it, so you could restore 
it if necessary.

I once had a similar py2.2 installation on my HP, but I deleted it 
several years ago as I never used any program that used it.
