Becasuse when I try, I get internal server error (code 500) stating that the web.config wasn't found...
Has anyone done this before and succeeded? I installed php through the web installer.
it shouldn't be a problem, i have wordpress, mediawiki running off a virtual directory in IIS7.
what application is it ? can you create a new directory on your desired location, put your php app over there and map it to a new virtual directory with a diff name ?
also check your php.ini and see if short open tag is off then switch it on:
you can check your loaded PHP.ini path via php info in a web browser : copy and paste this in a text file and save it in your web root, browse to it :
Hope that helps
