Installation Problem on Yosemite (MacOS 10.10)

Question

Running Yosemite (10.10). Using Safari Version 8.0 (10600.1.25)
Not working here in any form. The offline installer quits at 40% and the online installer returns "process not elevated". I've uninstalled Flash and that had no result.
I see a few entries like this in the system logs:
10/20/14 01:43:46.492 Adobe Flash Player Install Manager[7233]: Persistent UI failed to open file file://localhost/~/Library/Saved%20Application%20State/com.adobe.flashplayer.installmanag er.savedState/window_1.data: Permission denied (13)
Here is the relevant part of the installer's log:

It looks like the installer is trying to access that folder as if it were a Windows folder, instead of using shell escapes to include the spaces. A guess.
Also, the com.adobe.flashplayer.installmanager.savedState is only readable by "system" and no-one else. I cannot access it even as administrator.
Hope this helps.

Answer 1

I am using Yosemite on a MacBook Pro.  When I first tried to use an application that used Flash Player I was instructed to Upgrade the version of my Flash Player.  I tried to do this under both FireFox and Yosemite.  Under both scenarios I went through the update process just fine and at the end of the process the software advised me I had been successful.  I note that the same applications worked fine prior to my installation of Yosemite
I then ran Adobe’s Version checker which responded I had the latest version of Flash Player installed.
BUT
When I try applications that use Flash Player I am instructed to update the version of my copy of Flash Player that is loaded on my MacBook.  Also I am unable to find Flash Player via Finder>Applications
