Can I use one PhotoModeler license on two computers?

The PhotoModeler license is locked to a single computer.

For a single user, the license allows the program to be installed on two computers operated by that one user. Examples would be an office desktop computer and field notebook computer, or an office computer and a home computer both operated by the same person.

The ability to install on two computers is not intended for two separate people to use. In that case, two separate licenses must be purchased.
