[Zope] Import Zope Problem in Zope's Python

Hi, having installed zope 2.6.2 on winXP my pythonpath contains: L:\Zope\Zope262\bin;L:\Zope\Zope262\bin\lib;L:\Zope\Zope262\bin\DLLs;L:\Zope \Zope262\bin\lib\lib-tk;L:\Zope\Zope262\bin\Pythonwin;L:\Zope\Zope262\lib\py thon;L:\Zope\Zope262\lib\python\ZTUtils But still I cannot import Zope in the IDE or Command-Window despite the Browse Tool finds zope.py in ZTUtils. What can be the problem? All Modules from L:\Zope\Zope262\lib\python are not found via import. I am quite clueless what to do? Does anybody know more? Thanks for your replies, --Elena
