New Mac Version Flash Player Download Hangs Up at 95%

Question

I've been unable to download the newest version of Flash Player to my Mac 10.8.5, because the download always hangs up at 95% complete.  I've tried restarting my computer without success.  What is going wrong and what do I do to complete the download.  Previously my Flash Player worked fine, but I was notified that I need to upgrade to the new version.  Now I have no Flash Player working.  Any help you can provide will be much appreciated.  Thank you.

Hello again, Mike.
Okay, I did as you said:
1)     I found the downloaded file in my Downloads folder that I downloaded from the Adobe website.  The file name is: 
AdobeFlashPlayerInstaller_12_ltrosxd_aaa_aih.dmg
2)     I then double-clicked on the icon so the Install Adobe Flash Player icon appeared.  I believe doing this is what you called "mount the dmg."  I this is not what you wanted me to do then I need an explanation of what mount the dmg means.
3)     The window with the Install Adobe Flash Player did not look exactly like the window in the PDF you sent me.  Instead of just showing a small icon in the upper left corner with the file name under the icon Install Adobe Flash Player.app, the window that appeared has a large red band withe the Adobe logo in the upper left corner and a large lowercase "f" in the right side of the red band.  The icon appeared below the red band and the file name was to the right of the icon and showed "Install Adobe Flash Player" and did not include the ".app" at the end.
4)     I then did a Control click on the Adobe Flash Player icon and which opened the same window that you showed in your response.
5)     I click highlighted on "Show Package Contents," which took me to the Finder window with the Contents folder.
6)      I click highlighted on the "Contents" folder and found inside slightly different list than you showed.  My list of contents inside the Contents folder is:
     _CodeSignature
     info.plist
     MacOS
     Pkginfo
     Resources
7)     Although the list was not the same as the list you identified, both your list and my list did include a folder called "Resources."
8)     I click highlighted the Resources folder and found a different list than the long list you identified.  I found these contents inside the Resources folder:
     app.bundle
     app.icns
     en.lproj
So … there was no COCOA installer to run … and I am still stuck and still need your help.
Thanks,
Bruce
