Eric ~ My Zope is up and running, thanks to you! It turned out there were two other Python-related environment variables, both of which I deleted:

PYTHONPATH = %SystemDrive%\IBMTOOLS\utils\support;%SystemDrive%\IBMTOOLS\utils\logger

PYTHONCASEOK = 1

So, just for the record (and the next unsuspecting ThinkPadder who comes along), in all 4 ThinkPad variables had to go - the two above, plus the first two you told me about:

TCL_LIBRARY=C:\IBMTOOLS\Python22\tcl\tcl8.4 TK_LIBRARY=C:\IBMTOOLS\Python22\tcl\tk8.4

Delete it and try to restart zope. You don't need to reinstall things. it's a run time problem, not an installation problem. On 1/31/07, Ken Winter <ken@sunward.org> wrote: Eric ~ Right you are! A ThinkPad R52. So I removed those environment variables, restarted the machine, invoked Zope, and. still got the same error, "No module named ImplPython". So I'm wondering: 1. Is it possible that you did anything else, anything beyond removing those variables, that might have brought about your success? 2. Do you think I need to reinstall Zope after making the change? ~ Thanks ~ Ken -----Original Message----- From: Eric Fu [mailto:ericfu88@gmail.com] Sent: Tuesday, January 30, 2007 11:58 PM To: ken@sunward.org Subject: RE: [Zope] Re: FW: Problem Starting Zope after Installation I bet you had the problem on a ThinkPad too. I had the same problem about the "No module named ImplPython" problem. After spending a couple of hours on it. I found out that the problem is to do with an default installation of Python 2.2 that comes with my ThinkPad. After I removed these two environment variables zope will start: TCL_LIBRARY=C:\IBMTOOLS\Python22\tcl\tcl8.4 TK_LIBRARY=C:\IBMTOOLS\Python22\tcl\tk8.4
