Cannot get my Avast to work!  Will not take my license number.  Flags as "invalid"  Know good and well that I am putting in correct number!

What version of avast do you have, Home/Pro ?

How are you entering the key (type or copy and paste) ?

Q: "Invalid license number". Why? http://www.avast.com/eng/faq-invalid-license-number.html Or Insert Registration Key - Video

Hi David,

I would like to share my experience here with avast license key. I just purchase three years license for avast! pro edition. The reseller send me an email with PDF attachment contain the license key.

I tried to copy-paste the license (as how it used to be on Home Edition, we just copy-paste from email). But it return and saying the license is invalid (in a pop up window). I tried couples time, but the result still the same, I don't know what to do, even after restarting my computer (without logic reason of course), I still found the same issue.

Then I noticed that the pasted code was not the same from the source code/key on the PDF file. It changed! I do not understand why. Then I manually entered/typed the license key. And it worked.

That is my story, I think that is my own mistake, but still I don't get it, how can the copy-pasted key could change

@Cahya >> don't trust your copy - paste, sometimes the white space have type into the license file. better if you do manual type the license

@ Cahya
I only have experience with the Home registration key which is in the email body. Why the reseller would complicate this by putting it in a PDF file is beyond me, perhaps to protect against it being copied

It may simply be that copying from a PDF file also copies other underlying characters, it would also depend on the PDF reader (Adobe, etc.) as to how it reacts to copying text from it, protecting its protected status perhaps. I have no such problem with FoxIt PDF Reader, see below an extract from the user manual and it is an exact match.
