Need Registry Help / Clarification on "Word (version XP or onwards) could not be found"

Question

In regards to "Word (version XP or onwards) could not be found on this machine" and the registry hack I have a few questions.
Current Set up: Windows 7, 32-bit.
LiveCycle ES2, All of the patches have been applied to LiveCycle ES2
MS Word 2010, winword.exe found in C:\Program Files\Microsoft Office\Office14\
I have read: http://forums.adobe.com/message/3983628
And I get that the only way to fix this is by doing this:
Problem is the Registry. LiveCycle searches only the following folders.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\10.0\Word\InstallRoot
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\11.0\Word\InstallRoot
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Word\InstallRoot
But word 2010 is under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Word\InstallRoot
So, solution is (for win x32):
Create following Path in Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Word\InstallRoot
create new "string value" "Path" with value "C:\Program Files\Microsoft Office\Office14\"
Quotes are not necessary.
The question I have is about what sections in the Registry need to have the Path added.
Is it only:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Word\InstallRoot
Or do these areas need it as well?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Word
And last:
Does the adding the Path apply to only the 12.0 or does this need to be added to the 14.0 folders too?
I've never played with the Registry, and after applying the hack to the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Word\InstallRoot folder, I still cannot import Word files.
So I'm guessing it is just my ignorance on how the Registry works, or I misunderstood something in the instructions.
Thanks for the help! 

Answer 1

Gave up on the whole scenario, and got the free LiveCycle ES4 upgrade when I updated to Adobe Pro XI.
Import functions from Word now work.
