LOPIX  Sorry, we are used to getting support requests through the forum (www.live3dpoker.com/L3DP_BB) or the support email (support@live3dpoker.com), not checking here for user help requests.

The answer to your question can be found at www.live3dpoker.com/118update.php where we have listed the steps required to uninstall the old version and install the latest software.

Posting a negative review does not make us respond faster, a simple email would have sufficed.
