I'm running Mac OS X 10.7.5 on a MacBook Pro. Recently, my Energy Saver mode has stopped functioning, and I can no longer open the Energy Saver Configuration Pane. When I click it, an Alert Dialog pops up with the message:

Preferences Error

Could not load Energy Saver preference pane.

I have attempted to reinstall the latest system update, and deleted

/Library/Preferences/com.apple.systempreferences.plist

and

/Library/Caches/com.apple.systempreferences

However the problem has not resolved itself. How can I fix this?

I've found the answer. The solution is to go to /Applications in the Finder, right click System Preferences, select Get Info, and check the box that reads Open in 32 bit mode.
