I downloaded the latest flash player from the abode website (for mac, safari, english). Download is fine. Installation proceeds to about 50% completion and then terminates with a "General Installation Error". Here's the configuration:
Mac intel core 2 duo 2.26 GHz
I downloaded the flash player uninstaller, and it reported a successful uninstall. Also checked for directories in /Library/Internet Plugins and the (Disabled) folder. No flash player components left.
Checked pop-up blocker (it's not set), system preferences (download apps from any source is checked). Also disabled norton auto-protect. Install still fails.
I'm out of ideas. Any suggestions would be greatly appreciated.
How i solved:
When I tried the excellent suggested solution, I received the error message:
2013-02-11 16:09:05.968 Adobe Flash Player Install Manager[1169:707] Unable to write data to file '/var/root/Library/Preferences/Macromedia/Flash Player/install_vector.txt'.
Once I had created the missing directory by typing the two commands:
"sudo mkdir /var/root/Library/Preferences/Macromedia" and
"sudo mkdir /var/root/Library/Preferences/Macromedia/Flash Player"
then running the installer from the command line using sudo, as suggested, did work.
Variant that worked for me:
$ cd ~/Downloads/
$ hdiutil mount AdobeFlashPlayerInstaller_11_aih.dmg
$ ls /Volumes/Adobe\ Flash\ Player\ Installer/Install\ Adobe\ Flash\ Player.app/Contents/MacOS/Install\ Adobe\ Flash\ Player
<the above step was to verify the location of the installer, to use in the next step>
$ sudo /Volumes/Adobe\ Flash\ Player\ Installer/Install\ Adobe\ Flash\ Player.app/Contents/MacOS/Install\ Adobe\ Flash\ Player
$ hdiutil unmount /Volumes/Adobe\ Flash\ Player\ Installer/
Thanks all for getting me going in the right direction.
This is what I get. It still won't install.

I did all this (full Flash uninstall, re-install 10.8.5 plus Supplemental, verify hidden mach_kernal at root level, Terminal Reinstall attempt, etc.) with the same result of hanging at 50% on install w/General Install Error.
Then, from a post under General Error Message when Installing Flash Player on Mac:
Having this problem on a fresh install of 10.8.2.
Thanks to @mrdredre, the solution for me was to go to System Preferences, Security & Privacy, General tab, Allow applications downloaded from - make it "Anywhere".
After doing that, I re-ran the installer and it worked just fine.
Crazy that Adobe would release this new installer w/o having it signed so it works without changing this setting.
Switched to Anywhere and everythig installed perfectly.
Afterwards, be sure to switch back to Allow Mac App Store & ID'ed developers.
MBP 2.2GHz i7
OSX 10.8.5 w/supplement
There doesn't appear to be a solution to these particular error messages from Adobe. I have followed the guidance from Adobe.com (uninstalled and re-installed) and then followed the guidance in this forum post and others using the terminal route, all without luck. I have no Flash functionality (other than in Chrome) which is extremely annoying.
My setup is MacBookPro Mavericks 10.9. Firewall is off (temporarily). No virus software. No remnants of Flash as far as I can tell. Logged into a administrator account.
Here's the log for "flash" from console:
