Drupal is an Open Source Content Management System that has been designed to run on a variety of platforms including on a Windows computer running IIS. To install Drupal into your account at MyWinHosting.com, follow these instructions:
First, download the latest drupal release from http://drupal.org and unzip it to your local drive. Once you've uncompressed the files locally, you can upload them into your main domain directory, or a sub directory using an FTP program.
Next, you'll need to log into your control panel and create a MySQL database. See Creating a MySQL Database for instructions on how to do this. Remember the name of the database, the server name and the username/password you use when you create the database.
While you are logged into the control panel, you should change the index file to index.php. You can find instructions for how to do that at Changing the Index Page
You should now be able to run the install script by browsing to http://www.yourdomain.com where yourdomain.com is YOUR domain.
The wizard will ask for your database information from the database you just created. Make sure you click the "Advanced" link because you'll need to change the server from localhost, the install wizard's default to mysqlN.mywinhosting.com, where N is some number (you can get the correct server name from the control panel where you created the database.)
Click the button to finish the installation process.
