I have been spending the past while trying to install Joomla on a server running Windows Server 2008. I have successfully installed PHP (using Microsoft's web tool for installing PHP with IIS) and MySQL and am now trying to run the browser-based installation.
Everything comes up green, I fill in the appropriate information regarding the site name, MySQL information, etc. and no errors are thrown. However, when I get to the step that asks me to remove the installation directory, I am unable to do so as Windows states it is in use by another program (I cannot fathom how this is true). Also, there is no configuration.php file that is created so if I were to manage to delete this folder I have a feeling that there would be problems.
I was thinking there was some kind of a permissions issue and have set the permissions for IIS_IUSRS to have read, write, and execute permissions for the entire folder that Joomla resides in but this has not helped.
Any help in this matter is greatly appreciated. ;)
EDIT: I decided to try and manually install Joomla by manually editing the configuration.php file. This has worked great and now I am certain there is some kind of a permissions issue going on because I am able to do everything that involves the MySQL database (create an article, edit menu items, etc.), but anything that involves making changes to Joomla installation's directory does not work (install plugins, edit configuration settings using the Global Configuration menu within Joomla, etc.) I have granted IIS_IUSRS every permission except Full Control (reading on the Joomla! forums shows that this should be enough for everything to work). This is confusing to me and I am quite stuck on this problem.
EDIT 2: The bizarre thing is that in the System Info under Directory Permissions, everything turns up as Writable but then whenever I try to actually use Joomla to, for example, edit the configuration.php file using the interface, it says it is unable to edit the file.
