Your RetainPro License Agreement grants you permission to run up to a certain number of concurrent instances of the program, based on the number of "seats" you have purchased. The software ensures that you do not exceed your maximum permissible number of concurrent instances by requiring that the software obtain "permission" or "activation" in order to run.
To provide the maximum flexibility, we offer two different ways for the software to obtain this activation:
1. ENERCALC's Internet Activation system
2. Manual Activation Code.
Both of these offers certain advantages, and comes with certain limitations. Refer to the individual FAQ topics on the respective options for more information.
