What last version of Google Chrome or Internet Explorer will be able to support flash before End of Life?

[Guest]

As Adobe will end support for flash at the end of 2020. Which is  last version of  Google Chrome and Internet Explorer will be able to support it and from which version flash is not supported at all.

Those are questions for the browser vendors, not Adobe.

For Chrome, Google has posted a Flash support roadmap, Flash Roadmap - The Chromium Projects

I don't have a similar link for Internet Explorer.

you will not find a link for something about Flash in IE because a Microsoft security chief discourages using Internet Explorer as a default web browser earlier in 2019:

The perils of using Internet Explorer as your default browser - Microsoft Tech Community - 331732

now support for Internet Explorer from MS depends on the version of Windows used.  see this Microsoft Lifecycle FAQ for Internet Explorer on their support site:

https://support.microsoft.com/en-us/help/17454/lifecycle-faq-internet-explorer

realize that Microsoft is no longer making any newer versions of Internet Explorer since the release of IE11 several years ago

Essentially I'm looking to know if we can continue to support an app written in Adobe Flash beyond the end of 2020 by using an older version of a browser (ie. If we choose not to update the browser from IE11 as they are in citrix controlled environment ) will flash still work on such IE11?

Though, as Adobe will no longer distribute the flash , so a person running  IE11 within Citrix environment in 2021  will not be  to download Adobe Flash from your site , but the old installations  of Flash in control environments will still work .

The user with IE11 does not and cannot (usefully) download Flash, it was bundled by Microsoft, and they will stop that.

Microsoft say "By the end of 2020, we will remove the ability to run Adobe Flash in ... Internet Explorer across all supported versions of Microsoft Windows. Users will no longer have any ability to enable or run Flash." 

It seems to be that a truly frozen system MIGHT be immune - one cut off from the internet, content to never install Microsoft updates of any kind. It may be that this is not viable in a fairly short term, but it depends on your model.  If you install updates, Flash support will go as promised. It's entirely possible that the cut off date was already hard coded in a patch that was already shipped and is on your system! I wouldn't build any bridges on the assumption you can ignore this cutoff date.

Theoretically, a frozen VM that has currently supported OS and browser's should work.  In this case, this system should be behind a firewall that NEVER communicates with the outside world, for security purposes.  While Adobe will drop support for Flash (meaning no more security updates, etc), and stop hosting the installers on their website, the reality is that folks will hang on to old installers and versions of Flash Player that will most likely be exploited by malicious actors.

Microsoft only embeds Flash Player in IE on Windows 8 and above and Edge on Windows 10.  If it's a Windows 7 system, there is no bundling.
