You must be an Administrator to change the Registry so ensure you are logged
on when you try to use the patch. If it's a simple zip file, unzip it, if
you have a file inside that has a *.reg extension, AND you are the
Administrator, you can right click on the file and select MERGE.

Of course you should not be doing this if you are uncertain of the patch's
origin.
