I have placed a few threads out there with reference to this problem.  However, I found another fix to this.  You'll have to pay attention and follow the instructions to the letter though.

Official Patches sometimes give this message even when run as administrator.

Go to the folder "C:\Program Files (x86)\InstallShield Installation Information\"
Rename the {E51B4CD9-A0A6-4324-B26A-31B3F2DE26CE} folder by clicking on it, click to the end of the name and add a "1"
The folder should now look like this "{E51B4CD9-A0A6-4324-B26A-31B3F2DE26CE}1"
Run the official patch and you should get a different error message that states "To run this patch you must first install Black & White"
Go back to the C:\Program Files (x86)\InstallShield Installation Information\{E51B4CD9-A0A6-4324-B26A-31B3F2DE26CE}1" folder and remove the "1" to return it to normal naming convention.
Click back over to the patch that is still open and click "OK"
Run the patch again as Administrator.
The location of "C:\Program Files (x86)\InstallShield Installation Information\{E51B4CD9-A0A6-4324-B26A-31B3F2DE26CE}" is now cached and the patch should work.

You may encounter this a time or two more when installing other patches.  Just rinse-and-repeat.
