[Zope] installation of products with win 95

[Martin Hartmann]

Hello,
I tried to intall some products in zope (2.5.1) by copying the product 
folders to lib/python/Products: AbracadrabaObject, PropertyObject, 
PropertyFolder.
Zope runs under win95. If I start Zope, then there is an error message:

"... Error Zope couldn't install PropertyObject  File 
c:\Programme\WebSite\lib\python\OFS\Application.py Line 609, in 
install_product
Import Error: No module named Property Object ..."

After that it is possible to work with zope unter win95, but without 
these products.
With Win2000 there is no problem to install these products.
Where is the mistake ?
Thank you,
Martin Hartmann
