create language 'plpythonu' on win failed

I can't solve problem with creating language python in my POSTGRESQL (9.0)
-------------------------------------------------------------
create language 'plpythonu'

ERROR: could not load library "C:/Program Files/PostgreSQL/9.0/lib/plpython.dll": unknown error 126
--------------------------------------------------------------------------------------

I used dependency walker for finding problem and i find, that plpythonu.dll need python26.dll (i have instaled python 27 on my PC).
I try install python 26 to folder with postgresql, but there is the same problem.

Is there somebody who is able to create python lang in postgresql on win??

I used google, but i can't find any advice solving my problem.

Thanks Je.
