Well, I downloaded the free version of Karino Vocal Remover and then I installed it. But the problem is that it's asking for activation serial number. I'll be very appreciative, if someone can tell me where to get this.
This application is not free. What you've downloaded is a DEMO version of the application. It's free to download and use but to unlock it, you need to actually buy an activation code. This can be done from the official website of the developer.
Why do I have to pay in advance without trying the software? Developers should provide a trial period for 7 or 15 days as all other developers do.
