The first thing you should do is download the ManagePLUS Gold installer, install the program, and try it. When first installed, ManagePLUS Gold will operate in trial mode for free for 30 days. After that, it will require purchase if you want to continue using it.
The trial is the exact same software you will use if you decide to buy a ManagePLUS Gold software license. And the trial is not restricted in any way—you have access to all of the program's features, and you may install it on any number of computers during the trial.
After purchasing a ManagePLUS Gold license you will receive a license Registration code by email. This code is your unique, personalized "key" for unlocking the ManagePLUS Gold trial installation, to continue using it as the full registered version.
To enter the code, click on Help > Enter Registration Code in ManagePLUS Gold's menu. Then follow the prompts and enter the code in the Registration window when requested.
The easiest way to enter the code is by Copying & Pasting it from the email you received after purchase.
