Normally the programs remain activated, till your license expires (if you purchased a one year subscription). Once you activate one of them, all other AVS4YOU programs will automatically get activated. With this license key you are able to activate any of the downloaded AVS4YOU programs. After acquiring one of them on the Buy Now page you'll receive an e-mail from us, where you can find some instructions for installing and activating the AVS4YOU programs and your personal license key. On our website two subscription types are offered. One can activate the AVS4YOU software only after purchasing a subscription. If you'd like to get rid of it, you should activate the programs. There is no feature or time limitations for them, the only limitation is our watermark banner that is included into all output files. It means that you can use any of the programs right after downloading and installing it. All the programs available on the website are shareware and require activation.
