Hi Johann and Cornelis, Thanks for your help. I still am getting errors though. I tried changing the registry settings to "C:\PROGRA~1\WebSite\bin\python.exe" "C:\PROGRA~1\WebSite\z2.py" -S -D "STUPID_LOG_FILE=C:\PROGRA~1\Web Site\var\slf.log" and got the error "Could not start the Zope (Web Site) service on Local Computer. Error 193: 0xc1." I also got this error with ZService.py: Traceback (most recent call last): File "C:\Program Files\WebSite\ZServer\ZService.py", line 159, in ? class ZServerService(win32serviceutil.ServiceFramework): File "C:\Program Files\WebSite\ZServer\ZService.py", line 166, in ZServerService file=open(path, 'r') IOError: [Errno 2] No such file or directory: 'C:\\ZServer\\svcname.txt' Any ideas? thanks, Kristina
