New avg tuneup installation

Hello, Gastone.
Thank you for choosing an AVG solution for your device but I regret to hear that you are experiencing issues with installing it. May I know what is the exact error code or message that you receive when trying to install it? Please try to run AVG Remover tool as suggested in this article http://support.avg.com/SupportArticleView?urlname=How-to-troubleshoot-issues-after-upgrade-to-the-latest-AVG-antivirus-product to remove traces of failed installation and then try to install AVG TuneUp - Unlimited.
