I suspect that you did not make 2.6 the default installation, so it did 
not make the registry entry pyparsing was looking for.  If pyparsing has 
any compiled C, you need a binary compiled and linked for 2.6.

I would not be surprised if per-user installation was dropped because of 
problems, especially with Vista.

Probably built by M.L.Loewis, who may chime in.
