WhatsApp stopped opening on my PC after the 15/10/21 update

[Phil777]

My PC will not open WhasApp since the update of 15/10/2021.
It is a great inconvenience to me.
I have searched the internet and got no joy. I rang my PC repair man to see if he could help but he couldn't other than ask me to bring my PC in for him to look at.
I did find a website named realmicentral.com/ who seem to be aware of WhatsApp problems and sent a message to them on their Message Form yesterday but no reply so far.
I said, "I've been without WhatsApp on my PC since 15/10/2021 so pretty fed up and looked on the internet for solutions but nothing I did made it open. Then . . . . found your website saying there was an update to WhatsApp on 15/10/2021. BINGO!
I have Windows 10 version 21H2 although it says H1 somewhere else. It also shows the update for 15/10/2021 but it says version 2.2140.7 which doesn't seem to match your numbers.
Also, when I right click on the WhatsApp icon in the bottom tray and then right click on it again from the small list it gives me a bigger list with Properties on it. Left click on Properties gives a big window with options. Click on Compatibility and it offers a box to tick next to "Run this program in compatibility mode for " and there offers a long list of Windows programs which end with Windows 8. No Windows 10? Is this a problem?
Anyway, I can't open WhatsApp since this apparent update on 15/10/2021. Is there anything you can advise me to do to fix this problem please?"

Is anyone here able to help please?

Thanks,

Phil.

There was a news article recently advising this would happen. It related to phones, but I wonder if you do not have a current OS on a PC, if the same thing is occuring.

"WhatsApp will end support on some old Android and iOS smartphones in 2021 according to reports.

The Facebook-owned messaging app will stop working on phones that are not running on at least iOS 9 or Android 4.0.3 operating systems."

On your computer? Years ago I couldn't run it on Win 10, but I haven't tried since.
If your "compatibility mode" ends in Win 8, try that.

If all else fails, Look at Viber - a similar alternative. It runs on Win 10 (the latest)
as well as Android. It's pretty popular, and I now run both it and Whatsapp, as I
have some Whatsappophobes as contacts

Thanks Rick, I have the latest OS on my phone and I have Windows 10 version 21H2 on my PC so I have no idea why it suddenly stopped operating.

It has been working on Windows 10 for at least a year and maybe even much longer. I don't have Windows 8 or any of the earlier versions.
I won't use Viber as it can be hacked easily by schoolchildren as it happened to my friend's wife.

Still no reply from realmicentral.

Right, well just found this article which is 100% accurate and I applied the solution and am now using an earlier version of WhatsApp on my PC, namely 2.2138.13.
Why? Because WhatsApp engineers have stuffed up big time with the latest version according to the authors of this article written just 3 days ago!

Good. And what I meant is to select Win8 in the compatibility box. You don't have to have/have had it installed.
