 <p>You cannot write to the install directory without explicit permission from the user.</p> <p>Here is the protocol instead:</p> <ul> <li>At first startup, check to see if there is a file in the local data folder (<code>ApplicationDataContainer</code>), if not, read in the file from the install directory.</li> <li>Write out a copy of the file to the local app data folder (Check out guides on <code>ApplicationDataContainer</code> for more info there)</li> <li>Edit this file freely.</li> </ul>
