[Zope] Failed to register as service on win2000

I uninstalled zope 2.7.0 and installed 2.7.2 on my win2000 system. The installer failed to register zope as a service. I can start zope in console using C:\Zope-Instance\bin\runzope.bat but I do not want to be doing this all the time. I tried to register PythonService.exe but that fails: E:\usr2\Zope-2.7.2-0\bin>pythonservice.exe /register Registering the Python Service Manager... Fatal Python error: PyThreadState_Get: no current thread abnormal program termination Was something left behind by the 2.7.0 uninstall that is messing this up? -- Les Ferguson Software developer Waitakere, NZ
