But first of all — did you copy conf/GlobalProperties.php.orig into conf/GlobalProperties.php?
Did not get that…
I also tried to make an install on my free host at http://x10hosting.com/, but received a similar error:
Warning: require_once(/home/eleee/public_html/wikidot/conf/GlobalProperties.php) [function.require-once]: failed to open stream: No such file or directory in /home/eleee/public_html/wikidot/php/setup.php on line 43
Fatal error: require_once() [function.require]: Failed opening required '/home/eleee/public_html/wikidot/conf/GlobalProperties.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/eleee/public_html/wikidot/php/setup.php on line 43
No offense, but I find it rather strange that such a prestigious application as Wikidot have not yet been tested on Windows, nor is much or even any support yet available for Windows, the most popular OS in the world (yes I know, probably not true for web hosting, but still).
Also, even though I know this release is meant to be great for learning purposes, I really feel like the install-process is way too hard to figure out for any non-tech users. With apps like Joomla! and SMF, I never ever had to even glance at an install document. I hope this has been improved for the 2.0 version, although I'd love to get started already with version one, seeing as I have big plans for Wikidot.
Hope this didn't all sound to harsh, I still think Wikidot is the best wiki to date :)
