Can you point me to the installer that you are using with the expired cert?
There are 97 occurances of "Flash" on my C drive. This one might be the best bet:
flashget184.108.40.2060en.exe, 6.07 MB (6,375,088 bytes), created 8/17/13. But I can't be sure.
Can you please give me a general idea of what file name format I am looking for?
Do you get a message with that information? When doing what exactly?
P.S. flashget is not an Adobe product. Flash Player is installed in C:\WINDOWS\system32\Macromed\Flash and C:\WINDOWS\syswow64\Macromed\Flash
