How do I enter my license number to the trial version of AVG PC Tuneup

I have downloaded the trial version of AVG PC Tuneup because I accidentally removed my subscription from my programs.  I have a License Number, but I can't find where to enter it so my subscription will expire in April, and I can renew at that time.

Where do I enter my License Number to update from the trial version to the subscription?

Esther,

Sorry for the trouble. To activate AVG PC Tuneup , open it -> Help & Support -> Activate product -> enter your license number.

If you can't get activate option, you may have installed Unlimited product which will get activated using your email address. We need to uninstall it and reinstall proper version. Go to Control Panel -> Programs and Features -> Uninstall -> remove AVG PC Tuneup.

Then use this link: http://files-download.avg.com/inst/mp/AVG_PCTuneUp_765.exe or refer this article: http://support.avg.com/SupportArticleView?urlname=How-to-download-and-install-AVG-PC-TuneUp to install your AVG PC TuneUp.
