Flash Player will not load on Win 7 x64

I having trouble getting Flash Player to work on one Windows 7 x64 box.  The installer seems to complete, but the IE add-on/BHO does not load.  Tried rebooting the system, removing the components completely, and get the same result.  Have tried system restore, but the PC doesnt have restore points far enough back to help at all.

Not sure why it will not load... at first I thought there was an issue with the IE9 install, but was told that it didnt work prior to that when IE 8 was installed.  Is there any way to reload just the add-in?  when reviewing add-ins in IE, there is no mention of the flash player item(s), but looking in the path where the FP stuff is kept, the file(s) for the add-in are there. Wasnt sure if this was a Microsoft Windows issue or an Adobe issue, so I thought I would start here.

What it says is

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}\

The registry value under that key called "Compatibility Flags" whose DWORD data value was 400 (Hex) / 1024 (Decimal),  I changed it to 0 (zero) and then restart IE and reinstalled Flash.

Flash is working just fine now!

DerekSchauland---It could be that you did not see the "I have read and agreed..." check box and link on that red popup with the Privacy statement.  They are quite hard to read.  If you do not click that, you can just proceed and think all is OK until you get the "Unsuccessful" message.
Also: Make sure you're not running MSIE x64 version. AFAIK, Flash x64 is still in beta stages.
You can try launching IE in RUNAS mode - Right Click IE icon and select Runas Administrator. Head over to the adobe website and try re-installing the software.   I have found that the Adobe Download manager does not launch unless Runas Administrator is used to launch Internet Explorer(x86), therefore the Flash does not install.
