I have installed everything that I could and gave permission to all of the files but I seem to be missing something help.

The first thing I get is this.
You must chmod 755 concrete/libraries/3rdparty/htmldiff.py and disable PHP safe mode.

Then I get this when trying t install on a win2008 server.

Unable to open config/site.php for writing
then I get this.

Warning: mkdir() [function.mkdir]: Permission denied in C:\inetpub\wwwroot\x\concrete\controllers\install.php on line 185

Warning: mkdir() [function.mkdir]: Permission denied in C:\inetpub\wwwroot\x\concrete\controllers\install.php on line 188

Warning: mkdir() [function.mkdir]: Permission denied in C:\inetpub\wwwroot\x\concrete\controllers\install.php on line 200

After that I try to redo I get this.

There are already 73 tables in this database. Concrete must be installed in an empty database.

What am I missing?
