After downloading flash player for firefox, saving, closing firefox, and running install from download directory.
The installation begins and then prompts that the install failed press retry. That does not work.
I have uninstalled the older version of the plugin and updated Firefox to Version 39.
Thanks for any help!
Grab the Uninstaller here:
run it; it will uninstall ALL flash player versions ( except for IE in windows 8.x and above )
Next let make sure you have the correct processes closed.
Open a CMD prompt Run a Command as Administrator from the Windows 7 / Vista Run box
copy/paste the following one by one or make a bat file to do it all in one step How to Write a Batch File (with Examples) - wikiHow
taskkill.exe /im plugin-container.exe /f
taskkill.exe /im firefox.exe /f
taskkill.exe /im iexplore.exe /f
taskkill.exe /im flash* /f
taskkill.exe /im battle* /f
taskkill.exe /im steam* /f
Next try installing the files at the bottom for Firefox NPAPI one. these are the real installers not the online ones
Hopefully that helps
