The first time you run the program you will be asked to activate it by entering the 16- digit key we provided you. When you click OK, Design-Expert will connect via the internet to our activation server and authenticate the license.


If you know that you are using a network license, choose the Use network license and click on OK. See the Network Installation documentation for more instructions.

Activation Options

For unusual circumstances, there are four utilities available in the Options menu. These options allow for copying an already existing license file, activating by email for a specific Host ID, setting the HTTP proxy and deleting old license data.


Activate by email

If your computer can’t reach our server via the internet and you are unable to perform the manual activation procedure described above, you will need a license file sent to you. Click on the Options menu and choose Activate by email to send the 16-digit serial number and Host ID to us. If you do not have an internet connection, or if your email client fails to launch after clicking OK, email Include your serial number and the Host ID reported in the Activate by email dialog.


Copy license

We will reply to valid email activation requests with a license file that will activate your software. Use the Copy license option to copy the new license to your computer. Activate by browsing to the location of the license file then clicking OK. The license file will be copied to the proper directory on your system and the program will be activated.


Set HTTP proxy

If you know that your system has a proxy server, you can enter the host name of the proxy. Click on the Options menu and choose Set HTTP proxy. The host name should be entered in the form host_name:port_number if the port number used by the proxy is not the default 8080. If you need to set the proxy credentials, they can be entered in the form user:password. Note that only BASIC authentication type is supported.
