Please visist http://manage.i-waydomains.com where I am using domain registration control panel, For hosting I use Helm and Cpanel. Does Client Exec is compatible with that? I like to install this at www.i-waydomains.com which is currently running on a windows server.
Client Exec should run on your server as long as you have ioncube loader, and the latest versions of MySQL & PHP. Currently it will auto-create accounts with cpanel, but I am unsure about helm (there could have been a plugin made for it.)
