Hi, Tony.

Our plugin is capable of auto-updates, and for majority of our users, it works.

If the auto-updating does not work, that is not an issue coming from our plugin.

If you activated the purchase code in wpDataTables Settings/Activation, 

the update should be offered in the Plugins section. 

On some WordPress installations, 

you need to deactivate the plugin first in order to see the update offered, so please try that.

If that doesn't work, try going through Dashboard/Updates. 

See if you can update the plugin through there, and if that doesn't work either, you can follow the manual update procedures below.

Updating the plugin to the latest version

Let us know if you have any additional questions. Thank you.
