I missed the last update. How can I get it?

If you have a valid license for GLHEPro V4.0 or V4.1, the current update, v4.1.6 can be received by emailing glhepro@okstate.edu and requesting a link to the latest update. The updates are sent electronically, and you will have to un-install and re-install the program. So long as you are using the same computer, your previous registration code should still work.

If you do not have a V4.0 or V4.1 license you can purchase an upgrade from IGSPHA. Ordering information can be found at https://hvac.okstate.edu/glhepro/ordering-information .
