You may have seen plenty of announcements over the past few years about Adobe Flash coming to the end of life. Various browser manufacturers announced they will disable Flash. Microsoft announced they will uninstall Flash from Windows using a Windows Update (although only the Flash that came automatically with Windows, NOT user-installed Flash). Apple completely disabled Flash in Safari. Below is the dreaded Flash End of Life logo that you will see once Flash is finally turned off:

Yes, I agree with Steve Jobs — Flash is buggy and not secure. However, there are many IT manufacturers out there that used Flash to build their management software interfaces. Some common examples are VMware vSphere, Horizon, and HPE CommandView. That management software is not going away, even though most of it is older. In fact, some of these Flash-managed devices will be there for the next 10 years. So, what can the desperate IT administrator do to manage his or her devices?

Adobe sends users for extended Flash support to a company called Harman. HPE charges money for older CommandView support. Do not pay any money to these companies to use Flash.

Preparation

I am not recommending Chrome or Edge browsers for the below solution because they will auto-update and newer versions will not support Flash at all. Further, turning off auto-update in Chrome and Edge is difficult.

Here are 3 methods to get Flash running on your favorite website. Windows methods assume 64-bit Operating systems. If you want to try 32-bit Windows, the files are available, but the functionality has not been tested (although it will probably work). All the files talked about in these methods are downloadable below:

Google Chrome (finally?) reduces memory and CPU drain. While a few days ago we were singing the praises of all the novelties of the latest version of Firefox, today it's the turn of its number 1 rival: version 57 of Google Chrome arrives with several new features, foremost among them a savings in the memory and CPU consumption. Chrome will only sync this data on your approved devices, so you can rest easy that your information is safe. CPU usage is immensely important when choosing a web browser.

Method 1 — Microsoft Windows, if you have Internet Explorer browser and Flash already installed

This method applies to many older Windows Operating systems like Server 2008, 2012, 2016 and Windows 7 and even older Windows 10. It assumes a 64-bit operating system.

  1. Do NOT upgrade Internet Explorer to the Microsoft Edge browser.
  2. Set Internet Explorer to be the default browser in Default Programs.
  3. Download the mms.cfg file.
  4. Open the mms.cfg file with Notepad.
  5. Edit the URL on the right of the Equals sign with an address of the Flash website or file that you need.
    1. Ex. AllowListUrlPattern=https://localhost/admin/
  6. If you need additional websites, place them on the next lines, like in this example.
    1. AllowListUrlPattern=https://localhost/admin/
    2. AllowListUrlPattern=http://testwebsite.com/
    3. AllowListUrlPattern=*://*.finallystopflash.com/
  1. Save mms.cfg file on the desktop.
    1. Important: if you did not use my file, but you are creating the file yourself, makes sure in Notepad Save As dialog, you select “All Files” as the type, and “UTF-8” as the Encoding.
  2. Copy the mms.cfg file into the following directory: C:WindowsSysWOW64MacromedFlash
    1. That disables Flash updates and allows to use Flash on specified websites.
    2. If you don’t see this directory, it means Flash is not installed and you need to use Method 2 instead.
  3. Restart the Internet Explorer browser.
  4. Go to your website.
  5. This will open Internet Explorer with Flash functional.

Method 2 — Microsoft Windows, if you don’t have Internet Explorer and/or Flash installed
