If you wish to reinstall your script, first you have to remove your current installation in order to avoid any errors caused by the existing files in the installation directory.

If you need any of the old data, it is highly recommended to back it up before deleting it.

The uninstall process consists of the following steps: 

• Drop the MySQL Database
• Delete the directory /home/your_cpanel_user/public_html/$DIRECTORY/     (where $DIRECTORY is the name of the script directory)

If your script is installed in public_html, do not delete the whole directory. Simply delete all files related to the script.

Once the script is uninstalled, you may install it again in the same folder.
