hi, I was wondering how to have multiple instances of python running on XP. I have ZOPE and TSW installed, but ZOPE's python is grabbing paths from TSW's python. specifically I changed to dir "...\Zope-2.7.2-0\bin" and in cmd window ran python did help() , sys and executable= r'...\Zope-2.7.2-0\bin\python.exe' but exec_prefix = r'...\TSW\Apache2\python' path_importer_cache = ...\TSW|Apache2\python... TSW's pyhon is ver 2.3.4 ZOPE python is 2.3.3 so Is there a way to prevent this mixup? I would like to have ZOPE installed as a service, and that means a python is running as a service. I would like to multiple python services running, and have them stay in their own installed areas. Is there a way to define the internal paths, and not to use XP's search PATH Would I have to rename python to python_1, Python_2, etc? Thanks.
