From FAQ:
“Q: I was successfully registered for using avast antivirus program and I received the activation key. However, when I try to enter the key, the program says “Invalid license number”. Why?
A: The activation key is valid. Use copy & paste method to enter it into avast!; keep in mind that this number can´t be used on any server operating system. Besides, you have to be logged in Windows with administrators rights (to enter they key).”
The same problem - no answer above!
Win98SE; no server (alone home PC).
I received license key and used avast!4… four days!
However, after ‘bad’ shut down today, I cannot start it again!
It shows me “License key is not entered” pop-up window; I click “OK”;next window - “Registration” - I ‘use copy & paste method to enter’ the key (from “avast! Registration” mail); next time click “OK”; and…“Invalid license number” at the end !!!
What’s going on?
How to fix this?
