End of support for Windows XP/Vista

[NON]

It's a bit off-topic but for notice: Microsoft removed required databases for Windows XP/Vista (more precisely, SHA-1 hashed ones including Windows 7) to use Windows Update, so you can't use Windows Update for installing patches when you perform factory reset.

Thanks, NON, I halfway expected that would be true!  I wonder what will happen when I try to activate the registration (this time).  I suppose I could run a search on that; it doesn't reflect an Avast AV query, exactly!

Kiwi, if "normal" activation doesn't work for you, there is a Registry trick which has worked for me in the past.  It's a bit complex, but let me know if you want to try it (no guarantee).

Thank you again, Dix Huit!  Although I would have preferred to use an AV that I am used to and have trust in, an Offline Install seemed to be a must, however, it seems it was just not to be the way I wanted. 

In order to provide for the occasional exposure, and to see about Activation, I wanted protection before ever plugging in the ethernet cable from the router!  The Avast Offline installs I tested had problems.  I was forced to choose another AV, regrettably.  The Activation went through without a hitch.

All the rest of the helpful folks here, DavidR and Rocksteady, of course, glad to meet you!

You're welcome, good to meet you and good luck in the new AV.

[Dix Huit]

You're welcome, and good to know that XP can still be activated.  I hope you don't run into any more trouble and will soon be happily gaming.

Beginning on December 1, 2018, new Avast/AVG Antivirus products will no longer be delivered for the Windows XP and Windows Vista operating systems.

https://forum.avast.com/index.php?topic=220639.0

This means that as of  December 2018, existing users on the Windows XP or Windows Vista OS will remain on version 18.8 or older rather than
migrating to version 19.1 scheduled to be released in December of 2018. However, please note that all Windows XP and Vista users will continue
to receive virus definitions updates from the Avast Threat Labs database after this date and Avast/AVG Antivirus versions 18 and older will
continue to work as usual providing full protection,  but will not receive regular automatic updates of new program versions with new features.

Crap version 18.8 or older I want the newer version as install the older version does nothing as it won't install as its to old.

My main computer is Windows XP.

I know what your going to say that's on old OS, I don't care if its old it works how I want it to work.

Avast Premium Security 20.5.2415 (build 20.5.5410.561) last time I checked.

Avast Free Antivirus 18.8.2356 (build) 18.8.4084.409)

Free version or now the taskbar icon shows its not protected so the free version doesn't protect anything?

I can scan a file or folder and it shows it there is a problem.

Virus definitions version: 201114-2

Current version 20114-2

Release date 15/11/18

Latest update 14/11/20

Avast Premium Security 20.5.2415 (build 20.5.5410.561) on my Windows 7 laptop.

So I want the same on my Windows XP computer that is what I pay for.

Which is due for renewal I know.

Subscriptions is another long thread which I have made as bad as Avast is the forum is just as bad for my posts just like Avast itself, its like a Google search. If I made a post it should show the thread I made not what I posted. If I click on the link shown it just opens the thread I have to look at every post to see where I've posted my comment.

The ONLY reason I use Avast is because the license can be used on 3 computers. That is the only good thing about Avast.

All other anti-virus companies charge you for every computer you have.

Where to download last version for processor without SSE2? (the above mentioned version (post #1) is not installable)!

[rocksteady]

...the above mentioned version (post #1) is not installable.

I assume you downloaded the offline installer from the links provided.
What error do you get?

The installer files are also available from bob3160's Google Drive share if needed.
See:
https://forum.avast.com/index.php?topic=220639.msg1533473#msg1533473

Other (old) versions can be found on filepuma. 18.5 is preferred by some over 18.8 which may hog CPU.

... error message:

"We are sorry but Avast Antivirus cannot run on your computer because your processor does not support SSE2 instruction set."

This happens both with online or offline installer and also when running that version of avastclear in the mentioned link (to uninstall an older version).

For sure it would fail with the on-line installation file as that only runs the latest Avast version for your OS.  That said if the last version of avast supported for your OS doesn't have CPU support for SSE2 it would fail.

You will have to go back even further to find a version of avast that doesn't require SSE2, filepuma.com may be your only option. 
Unfortunately I don't know what was the last version that didn't require SSE2, so it may take some trial and error, stepping back a whole version, 17.x, 16.x, 15.x etc. until you get to a point that you don't get this installation error.  It may even as far back as avast 10, 11 or 12, so this is no easy task.
