Here is a link. Not sure if will help, but helped me.
Add Take Ownership Option Shortcut in Right Click Menu of Windows 7
Go down to the link that says download "take ownership"
Unzip the file, using WinRar.
While in said user account, go to the files you unzipped, double-click the "install Take ownership.reg"
It will install a right-click option in the context menu that allows you to take ownership of a given file or folder.
BE ADVISED: maybe make duplicates of the .exe files in question in case it doesn't work. Or you can re-download them again I guess.
If it works and you are done and happy, you can double-click the "removeTakeownership.reg" and it will remove the entry from your registry as well as the option in the right-click context menu.
