AVG Password Protection

I have tried to install AVG Password Protection on two different computers I own and it says it is installing and after a while it just goes back to the item lite up in green stating activate & install. I paid to have this program and can not use it please help.

Hello Mabel,

We're here to help. 
AVG Password Protection installs and activates automatically when you activate AVG Internet Security.
Open the AVG Internet Security and go to ☰ Menu ▸ Password Protection.

To ensure Password Protection is enabled and actively protecting your passwords, click Hacker Attacks on the main AVG Internet Security screen. A green (ON) slider above Password Protection shows that the feature is enabled.
Thank you.
