Total product quality, reliability and ease of use are our top priorities. Because of this, you probably won't need much technical support. In the event that you do, the fastest path to our support engineers is by e-mail at the following address:


Express Logic customers are encouraged to register HERE to receive notifications of the availability of product updates, as they become available from Express Logic.

When sending support e-mail, it is important to supply us the "Version ID String" of the product you are using. Be sure to copy the entire string, which includes valuable information on the tools for which your version was produced. The following table shows how to find the Version ID String:
