With your purchase of any ERA 4 product, you have received an e-mail with the product key(s), which you can also retrieve any time from the Perpetual licenses tab of your accusonus account.
Accusonus product keys consist of 28 alphanumeric characters as shown below.
The first time you open an ERA 4 plugin, the Evaluation screen will open.
1) Check I'm Online and then click on the Activate button. The Activation screen will open.
2) Enter your product key in the corresponding field and then click Activate.
3) Enjoy your product!
The type of your license will also appear on the accusonus toolbar. After the activation, Standard, NFR or Educational label, depending on your license, will appear on it.
