Help please on installing Avast Cleanup on second computer

[Preston15]

I just bought Clean up for 3 computers.  I downloaded the exe file and installed it on my PC and had no problem. I use Windows 10
My second computer runs Windows 7.  (Wife's computer)  I forwarded the email I got from Avast that has the download link and installed it on this computer.
I ran the program and it scanned and showed all the item needed fixing.
When I clicked on fix it took me to a purchase screen showing prices for the program.
I already paid for the program for 3 PC's
There is no place for my to enter the activation code on the Avast cleanup I installed on my wife's PC
I could not find a fix in the FAQ's
What can I do to get the program working on my second PC?

Hi,

Our system shows that you have only installed it on 1 device thus far- can be installed on two more Windows devices.
Seeing that both devices are Windows - Cleanup's UI will be the same.
If you open Avast Cleanup > go to Menu > My licenses

Thanks for your response.

I have uninstalled the product from my wife's computer
restared the computer
reinstalled Clean up

When I open Clean up it goes right to an option to begin a scan (or skip)
Nowhere on the opening screen is a provision to enter the activation code.
On my originial install on my computer there was a menu icon to click on so I could enter the code
This does not show on my second install on my other computer

If I do run a scan on my other computer it gives me a list of the problems to solve but when I choose to solve these problems I am taken to a purchase screen (the one that I used to buy the product for multiple PC's

Something is missing and I cannot figure out what to do to get the activation code on my second computer.

Please help me get this done..thank you for your help

"I got the program installed on my other PC.  The problem was the screen resolution on the PC..."
