Strange error during installation of the newest AVG Tune'up

Hello
Today I had opportunity to upgrade my AVG PC TuneUp utility (previously I had 2015 version of that one). I bougt a license key and started installation (with the file AVG_Performance_803.exe).

Unfortunately error with number 0xc007001d occurred (just like with AVG Internet Security).
My system is Windows Vista Ultimate SP 2 , I and use permanently Avast Free Antivirus Home Edition.

Do you know, what is the clue?
Best regards
Wojtek

Hello Wojciech,
I understand the inconvenience caused. I am sure we will be able to fix this together. Please check the AVG programs you have installed on your computer (open control panel > program and features), if you have already installed AVG TuneUp program then please uninstall it (the error might be because of AVG PC TuneUp traces) and follow the instruction (http://support.avg.com/SupportArticleView?urlname=Download-and-install-AVG-Performance) to install your AVG TuneUp - Unlimited program.
Best regards,
Alok.
