iprntman for Windows not working with OES11

Hello,

I try using iprntman for windows downloaded from my OES11 box, but I get this error:

Error: class does not exist (Class not found)
Exception encountered in \w32\ow_cvs\src\client\OW_CIMXMLCIMOMHandle.cpp on line 329

Using iprntman for linux is working fine.
I wondering about the versions.
iprntman for windows is version 1.0.20051121
iprntman for linux is version 2.0.1

On an OES2 box iprntman for windows is the same version 1.0.20051121
The linux version is 1.1.0 build 20111109

Could it be, that OES11 will ship with the wrong iprntman for windows?

regards
Chris
