Hi to all.
I have an Operating Sistem Windows XP,
Php 5.0.1 is installed over IIS 6 and works fine,
MySQL 4.0.17 idem.

Now I have created a folder in the drive c:\ named xoops,
in this folder I've copied files and folder extracted from directory 'html' xoops-2.0.7.3.tgz so as they are, the files /folder in c:\xoops are in R/W for everyone.
I've created new virtual directory that point to c:\xoops.

Finally I've called the installation procedure froma my browser so:

http://ComputerName/xoops/index.php

the CMS reply with new address and with 'welcome module'
http://ComputerName/xoops/install/index.php

then if I click on the [NEXT] button the CMS reply with the same page.

Where I mistake ?
An Idea?

Thanks to all

Probably due to PHP5 not recognizing HTTP_XXX_VARS by default (it's in the php.ini somewhere, I believe, and is called something like "long var names")

XOOPS does not claim to be PHP5 compatible and we do know that there are things not working - so do a search for PHP5 compatibility and you should find some more hints on how to get XOOPS working with PHP5.
