Here's my solution:
1.) After you get the "PATCH FAILED" pop-up window, click "OK" to close it.
2.) Double-click the patch again.
Repeat steps 1 & 2 until it installs. You might have to do this 3-4 times.
The first time, the install meter went up to 8% and failed. I closed the "PATCH FAILED" window, then double-clicked the patch again, and the install meter went up to 12% then failed. It eventually installed.
