I have an active subscription for AVG Ultimate for 10 devices, currently being used on only 4.  It is RIDICULOUSLY difficult to figure out how to install it on my daughter's PC (that I own). 
You should have a link from my subscription page to let me send/share installation with a device via email AND make it very clear that I don't have to give you another credit card to download the free version and then change to the active subscription.
You used to make it easy to do this - why did you change?  
Even the instructions for Activating Ultimate Subscription Bundles takes me in circles.  It looks like it would be helpful but it is not. 
This is making me mad enough to change to a different provider, and I've been an AVG user for 10 years or more.  
Suggestions?
