title: MySQL keyring_file not found (Errcode: 13 - Permission denied) on WAMP64 MySQL 5.7.19
body: <p>I’m running WAMP64 on Windows 10 (development machine), with MySQL 5.7.19.  I’ve installed the keyring_file plugin.  MySQL starts, but the keyring_file is not found, so the following errors: </p>
  
  <blockquote>
    <p>[ERROR] Plugin keyring_file reported: 'File
    'C:/wamp64/bin/mysql/mysql5.7.19/lib/plugin/keyring_file.dll' not
    found (Errcode: 13 - Permission denied)' [ERROR] Plugin keyring_file
    reported: 'keyring_file initialization failure. Please check if the
    keyring_file_data points to readable keyring file or keyring file can
    be created in the specified location. The keyring_file will stay
    unusable until correct path to the keyring file gets provided'</p>

  <p>The file is on the specified path:

  <p>And the mysql service has Local System permission:

  <p>I have tried uninstalling and re-installing the plugins, granting broader permissions on the keyring.dll file, and of course I have re-started the MySQL service after each test.   </p>
  
  <p>So my question is why am I getting Errcode 13, permission denied?  What am I missing here?  Thanks.  </p>
