Before going any further, you will need a license for your ClientExec software. You can obtain one directly from ClientExec if you purchased directly from us or by one of our many resellers whom you probably obtained your license from. If your hosting company does not provide ClientExec make sure you let them know you would appreciate that value added service.
If you have already purchased a license, then you will already have submitted the domain name that you wish licensed. The good news is that you need do nothing else! You can use any subdomain on the domain that you selected to be licensed (ie: client.yourdomain.com or members.yourdomain.com).
If you have yet to purchase a license please visit http://www.clientexec.com/pricing.php or submit a support ticket via email to [email protected].
