[Zope] install of 2.4.2 on NT4 fails

I tried to install zope 2.4.2 on an NT4 box. The install fails immedialtely with an "internal error". The box is NT4, sp6a + security roll-up, NWClient 4.81 and Netshield 4.5. AMD K6-2/500MHz with 256 MB of memory. Any idea why it fails? ====================================================================== /Jan DE RYCK, Systems Engineer College of Business Administration, University of Hawaii at Manoa ph.
