Update to 8213 Release failed

Update to 8213 Release failed

The installation of the update failed and I was required to roll back to get things working again. I'd like to try the update again, but now I get a message that the selected servicepack is already installed. The Help About menu shows 8212 is what is installed and 8213 is available, but I can't run it. Is there any way to "trick" the software into thinking the update was never applied?
