The following are version details of the TWiki, Perl and Apachae that I used:
TWiki : TWiki-5.0.1 Perl : ActivePerl-5.12.3 Apachae :Apache2.2 OS: WinXP Professional 32 bit SP3
For the section of 'Apachae2 configuration', I tried placing the line 'Include conf/twiki.conf', first within the '</IfModule>' than also outside of it. I am still not able to get Twiki up and running, by that I mean when I go to the following URL: 'http://localhost/twiki/bin/configure', I get a HTTP 404 not found error. I hope someone can advise me. Thanks.
