A little about me. I been doing desk-side support in EDU for over a decade. I have extensive hands on experience with troubleshooting machines mostly Windows based. I write code which should be evident from this posting, and have managed people as well. I consider myself a professional in the IT field with that much experiences as well as a degree in the sciences as well as A+ certified.
I have created a simple set of commands that can be ran that will do the following which is based off the official Adobe method located here:
1) Full uninstall of ANY Adobe Flash player versions install. That is for IE or a plugin based browser such as Firefox. The bat/cmd file method has been tested on Windows 7, and Windows 10 technical preview, but should work on Windows 8.X without any issues.
2) Removes all traces of anything Adobe Flash related from the following folders(except win 8 and above):
b) C:\Users\%username%\AppData\Roaming\Adobe\Flash Player
c) C:\Users\%username%\AppData\Roaming\Macromedia\Flash Player
3) Re-install your flash player versions.
I have written this in BAT file format b/c some people esp on the Firefox Forums are overly paranoid about exe, and it has become clear that some do not understand bat files either... I think I have a good enough following to prove i don't write harmful code.
I have greatly simplified this process to uninstall all flash player versions, clean up flash player files, and re-install the latest versions.
5) Go here and down load a bat file(Clean_Flash.cmd ) and place it in any folder.
6) Run as admin and let the script work, takes about a minute or so at the most to get started due to the protocol. Note" If it sites there for over two minutes something is blocking bitsadmin.exe so it is up to YOU to resolve that.
That is all there is to it, no more guessing games for flash anymore.
Please make sure all programs are closed.
I have a full exe that will automatically determine the DL file
regardless of the flash version. This exe has been cleared by Symantec
and TrendMicro as virus and crap-ware free. This version will NOT update
ActiveX version on windows 8.X and above that is handled via windows
Here is a link to the main page: https://sourceforge.net/projects/adobeflashupdater/
The exe can be downloaded there, its much faster than the bat file
method and dynamic for the download files, and does essentially
everything that the bat does and more, but you should never have to go
download a new installer when a new flash version comes out. You can go
to the post I have to read the changes and get the latest ActiveX Flash
versions for Windows 8.X and above HERE
SECTION 7 & 8 BELOW IS FOR MORE EXTENSIVE INTERNET EXPLODER TROUBLESHOOTING
7) IF you have issues where the ActiveX version failed to install on Windows7 , you might want to look at this article here:
https://forums.adobe.com/thread/987370 . As it is a permission fix for Windows 7 ONLY. I simplified this process down with a WinRAR exe file that will save the novice PC user about 10 minutes of frustration of fumbling through files and folder. Once again if you get winrar you can open up the file and see the contents. You can get that simplified fix here
8) If you still are experiencing issues with Internet Exploder I am going to post some additional links for you to go over in order of from easiest to most complicated.
a) Reset Internet Exploder
b) Check File system for corrupt files
c) Reinstall Internet Exploder
If it still fails after all that work, then in my opinion, maybe restore the Operating system to the Origional state
A note about the flash player versions:
The link is ONLY valid for Flash player versions 16.x.x.xxx . Once version 17 comes out the download file reference will have to be changed thought the script.
Here is a direct link to the msi installer files but you must read the terms.My installer does not use these msi files btw, but the ones you normally would use when going to adobe and doing the update, but the extra programs that adobe piggybacks on them is removed :)
I have some additional possible solutions for flash player crashing in Firefox if the Mozilla Forums prove useless as do for many for this issue.
