I have the ios premium version also installed on my laptop and my desktop pc, I change my laptop but I can not install in my one, does the license has a limit of activations?
Probably you've made mistake while was typing the key. The easiest way to enter the key without errors is to copy and paste it (select the key and copy it to clipboard by clicking Ctrl+C). Then paste it into the Key Activation field (click Ctrl+V). Click the Activate button and restart the program.
