Is there a way on the dashboard to know how many times my application trys to check if license is valid.

Is there a way to know (track) on the dashboard how often a program is ran by using IsGenuine().

No, TurboActivate can't be used for general "use tracking". Also, IsGenuine() should not be run on every start of your app. We recommend calling it every 90 days. Use IsGenuineEx() to do that.

A question to the topic:

OK, 90 days for online checkdoes it mean that once the key was deactivated, the user will still use the product using deactivated key up to 3 months?

If the user deactivates the key then they lose the ability to use the product immediately. If you remotely deactivate or revoke the key then the user will have a maximum of 90 days to continue to use the product. If you want to do a shorter length of time you certainly can, but we don't recommend going below 30 days.
