Installation help

The current products are Windows desktop applications. Download the installer from the Download page, run the setup file, and use the default installation folder unless you have a reason to change it.

Registration help

Power of Interest products use a one-time installation registration approach. Open Register Software in the program, copy the Installation ID, and follow the registration instructions after purchase. The passcode is specific to that installation.

Replacement computers

If you are moving registered software to another computer, contact support with the product name and the Installation ID shown on the new computer. We can review the available registration options.

Before contacting support

Please include the product name, version number if visible, and a short description of what you are trying to do. Screenshots are helpful when a window, printout, or calculation does not look right.
