Hi Evan, Hi all,

I made a cc to the zope list because other people could encounter the same problem and I couldn't find anything appropriate about the solution in the list.

I tried to make my life easier with INSTANCE_HOME as described in http://www.zope.org/Members/4am/instancehome. All seems to work fine. But Zope displays the following error on startup: 2001-02-13T09:41:49 ERROR(200) ZServer Cannot write PID file.

After some searching I know what happend. I _moved_ the whole var directory to my INSTANCE_HOME so zope couldn't write the pcgi.pid to the disappeared var directory anymore.

So I propose to mention the fact in your the How-To that at least a empty var directory has to remain in the original zope installation.

This note applies to Zope 2.3.0 (and possibly to former versions too) on a NT4SP6us machine.

Greetings, Greg

P.S.: Sorry about my emglish. It's not my mother tongue!

this is not true on linux where debian installation uses INSTANCE_HOME to put the var directory and other things such as the new installed products in /var/lib/zope and the code (without another var directory) in /usr/lib/zope, but the last zope package is for zope 2.2.4.
