Flashbuilder 4.7 and Windows 8.1 - Debugger not working

Question

I have recently upgraded to Windows 8.1 and am having problems getting both the debugger and the run to work for an AIR Mobile application in Flashbuilder 8.1.
In Flashbuilder the error message is 'Process Terminated unexpectedly' with the adl.ex launch command below it.
If I run the adl from the command prompt, the error message states 'Adobe AIR could not be found'.
However, if I replace the -runtime with an AIR download i.e. 3.9 that does not include the Flashbuilder Flex components, then the AIR app fires up correctly. I don't think it is a port problem as I tried with the firewall turned off and got the same results.
Is this a known problem with Windows 8.1? Has anyone else seen this issue?
Thanks

So, since Adobe is MIA and are giving even more arguments to the late Steve Job about the sory state of their player, here is what I found so far.
I was able to uninstall/remove the current player. Keep in mine that I am still trying to install the debug version. Also, I am not sure if all the steps are required as many attempts, trial and errors have been made. This is on Windows 8.1 - 64bit
Downloaded the uninstaller

Exit all browsers
Run the uninstaller
Take ownership of the folder and all sub-folders and files from...
C:\Windows\SysWOW64\Macromed\Flash
Right-click Flash folder, select properties, Security tab, Advanced button
Next to owner, select Change link
Type you user name and select Ok
Make sure to select the check box for "Replace all children..."
Give yourself full access to the same folder and files
Right-click Flash folder, select properties, select Security tab
Select Edit button
Select Add button
Type you user name and select Ok
Select full control check box
Select Ok
Now you should be able to rename the folder to "FlashOld".
Restart the computer
Test the player
With IE, go to...

This should confirm that the player is gone.
Reinstall
I tried to install the Windows 8.1 x64 debugger from
http://go.microsoft.com/fwlink/?LinkId=325411 but I keep getting the same message saying that MS IE will take care of the updates (Great, tx!!...not).
I tried
http://download.macromedia.com/pub/flashplayer/updaters/11/flashplayer_11_ax_debug.exe
and it appears to install without issues.
It created a Flash folder right next to the old one.
I restarted the computer but going to the test page shows that it does not work.
Still stuck...chime in anytime Adobe!!
