Cannot add 3rd computer

[REDACTED]

Paid for 3 computers, but not able to add 3rd one. Just get sales pitches.

The first two are working correctly ?

Have the license resend and try to implement it on the 3rd system.

If it doesn't work, please provide more information.
What os/sp?
What exact version of avast?
Any other security (related) software installed? (or had installed)
Any error message?
Other problems with the system?

How are you trying to apply the license to the third system ?
Essentially it should work the same as the first and second.
