The web installer needs to be able to create a file called ".htconfig.php" in the top folder of 
your web server. It is unable to do so. This is most often a permission setting, as the web server 
may not be able to write files in your folder (even if you can).

Please check with your site documentation or support people to see if this situation can be corrected. 
If not, you may be required to perform a manual installation. Please see the file "INSTALL" for instructions.
