I had this problem. You must run Lightroom as administrator - even if the account you are in has administrator priviliges.
Test if this is the problem you are having  by opening lightroom in administrator mode:
Open Windows explorer and navigate to where the lightroom.exe file is located.
Usualy in  C:\Program Files\Adobe\Adobe Photoshop Lightroom 4.4
Right click on lightroom.exe and select "Run as administrator" from the pop up menu.
Test by selecting a photo and selecting the "Edit in Adobe photoshop CS6" option.
If this works then close lightroom and go back to the "lightroom.exe" folder location,
rightclick on the lightroom.exe file but select "properties", then select the "compatibility" tab and
select "change settings for all users" button.
A box called  compatibility for all users should appear, at the bottom there is a checkbox "privilige level"
make sure the "run this program as administrator is checked".
Close lightroom and reopen it.
Hope this helps.
