Flash Installer choosing different versions of installer
I am running Windows 8.1 Pro. I use Firefox browser. Both are updated fully. I have Flash installer set to "Notify me to install updates." Occasionally I receive an Adobe notice as soon as I boot into Windows that an update to Flash is available. I tell it to install the update, it appears to proceed normally and I am asked to save an update file to my hard drive. This is all exactly how I want it to work, but every time this happens, the file I am given to download is named "flashplayerXXau_ha." However, if I go to the Flash website and ask it to check my version and download the latest update, the file I am given to download is named "flashplayerXX_xa." Why do the two files have different names? What is the difference between the two files?
