Invalid License Key

[grandmasterb]

Avast will not accept the license key that I received in an e-mail.

The key is:    C1848944H1400A0811-.....


Any suggestions?

I am using a Windows 98 system.

Hi grandmasterb,

Is this a home or pro license?
Where did you get the key?

I am not sure whether it is actually necessary to post the whole key really...

Can you double check the system time and date?

Do these help?

What build of avast! do you have installed?

[grandmasterb]

I have done all of that.

I posted the whole key because AVAST tells me it is invalid and I am hoping that someone call explain WHY it is invalid.

Thank You

i have the Avast! Home Edition 4.7.942

Honestly, I don't think anybody can tell you what it going on in that ancient version.
I suggest to update to the latest build first.

Well the avast version is way out of date, the current version is 4.8.1351 and that may contribute the problem.

So I would suggest that you do a clean reinstall of the latest version of avast.

Download the latest version of avast http://www.avast.com/eng/download-avast-home.html and save it to your HDD, somewhere you can find it again. Use that when you reinstall. Ensure that you scroll down and select the avast direct download link for the English version and not Cnet as that is for an on-line installation (not what you want to do).

Download the avast! Uninstall Utility, find it here and save it to your HDD.

• 1. Now uninstall (using add remove programs, if you can't do that start from the next step), reboot.
• 2. run the avast! Uninstall Utility, reboot.  If step 1 failed it may be necessary to run this from safe mode, once complete reboot into normal mode.
• 3. install the latest version, reboot.

Hi Guys i too am having this problem and have been for the past 2/3 weeks trying install avast without success. Done all the recommmended thing like check the date settings and still no luck.


Ended up here and deleted/uninstalled all the avast downloads i had on my laptop using David Rs tool just above my post and installed latest version of Avast and still its stillcoming back as invalid licence key


What could be causing this. I am using Firefox and Windows Vista if it helps :'( :'( :'(

Have you tried getting a new license key (and are we talking about avast 4.8 Home) ?
- Complete the avast! 4 Home Registration form and you will receive an email from register @ avast.com (without the spaces) with your registration key. Use the option I'm a registered user but my key has expired, that should ensure that you don't get a copy of the same key back.

Are these some of the things you tried ?
Q: My licence key has expired, what to do? http://www.avast.com/eng/faq-registration-license.html#idt_1442
Q: "Invalid license number". Why? http://www.avast.com/eng/faq-invalid-license-number.html Or Insert Registration Key - Video

DavidR i have tried all the things above from watching the video to see where i am going wrong to checking the date as well as checking if its latest version of avast and in all cases it cheks all the right boxes and yet still keep getting invalid licence. What could be causing this guys as i am at my wits end.



Have unstalled and reinstalled it about 5 times but still same problem

[DavidR]

So did you get a new license/registration key ?
e.g. did you check it was a different one.

If you re-register and input the same email that you used before it is possible you would be sent a copy of the one you have (compare the two). That is why I suggested you should use the "I'm a registered user but my key has expired" option.

I know I'm going over old ground but your answer was not detailed, but a I tried everything, call me fickle but I like to know exactly what you have done or I'm guessing.

[darkchild101]

Yeah they are different keys. Even tried registering with my other email address and was sent different key and yet the problem persists

Please, post the last 300-350 lines of avast log: C:\Program Files\Alwil Software\Avast4\DATA\log\Setup.log

OK, when you did the reinstalls, did you also run the avast uninstall utility ?

If not and there is nothing in the setup.log, a clean reinstall (I know) would be the only other thing I can suggest.

Download the latest version of avast http://www.avast.com/eng/download-avast-home.html and save it to your HDD, somewhere you can find it again. Use that when you reinstall. Ensure that you scroll down and select the avast direct download link for the English version and not Cnet as that is for an on-line installation (not what you want to do). - Direct download for avast Home, English version, http://files.avast.com/iavs4pro/setupeng.exe.

Download the avast! Uninstall Utility, find it here and save it to your HDD.

• 1. Now uninstall (using add remove programs, if you can't do that start from the next step), reboot.
• 2. run the avast! Uninstall Utility, reboot.  If step 1 failed it may be necessary to run this from safe mode, once complete reboot into normal mode.
• 3. install the latest version, reboot.
