Hi Thanks for posting this, I created the Windows installer script and one of my colleagues noticed this too, so we prepared a modified version. I have attached the modified win32_postinstall.py script ; and I have a rebuilt installer at http://davidf.sjsoft.com/files/mod_python-3.1.3-1.win32-py2.3.exe This also contains a fix for the attachment filetype problem. Please test and let me know if this fixes your problem David PS Grisha, is there time now to start getting this stuff into CVS, as it would be better management-wise? :-) Eddie Diener wrote: > Mod_python's postinstall script assumes that the Apache key in the > Windows registry is in HKLM.
