i'm not familiar with with ideawebserver; the main challenge is to redirect pages to /sapphire/main.php?url=XXX and ensure the right environment variables are passed. We got it going fairly easily with lighttpd; download the windows package and have a look...

Also, disable php files from being run in /assets/ as this is where uploads are put.

You may be better of getting a cheap (few bucks a month) US host if you're not up to the challenge.

You could help by installing 202rc1 and pasting us what it shown on the install page...
