License key

How and where would I apply my license key for FlowHeater Designer - Full Version?

Thanks

Have you received the automatic email with the license key file? If not please check your junk email folder.

From this email save the attachment "FlowHeaterDesigner.lic" to a local folder on your hard drive.

To activate, go to the menu option in the Designer "?->License" and click the button "Read license file"; selecting the saved attachment. The freeware version switch now to the full version you have paid for. Thanks.
