Hello, i’m using free home edition of avast 4.6, i have a correct register code. I’m using Avast for some years, and yet it says to me that the system upgrade will be off at April…so i retape my registration code, but it allways say “avast will expir at 1st april” :o…what the problem?..Do i have to register another account for having a update system??? ???
Hi and welcome guillard
Its ok for this to happen,although you have updated, the program requires you to re-register every 18 months, so all thats required is to visit the download page and re-apply for a new validation number. This will be e-mailed to you almost instantly.
In fact, it should be 14 months.
- Check your system date and time.
- The Registration key is valid for 14 months. Has this period expired? Register again (for free).
- Use copy & paste method to apply the key (take care to not copy the ‘last’ blank space at the end of the paragraph: copy only the key).
Oh ok…i didn’t understand that i had to re-register for a new number…i’ll do it…thanks a lot… ::)…also it’s strange that we have to re-register, but it sure something like controlling that the soft is allready in use by this user…thx all!!!
You’re right. 
And there’s special FAQ 'bout this: http://www.avast.com/eng/my_licence_key_has_e.html
The license key for home users is valid for 14 months. After this period you have to register again.
yes it works!!! :D…and it’s my fault … :-X…if i had given more attention the first time i registered, i new it…sorry for the time you lose by my fault… :-.…but thx a lot for it!!! 
this soft is the best i never had!!..it find more virus than anyone else!!..you do a great job!!!..
