Dual programs after 10.8.2

[qtrim]

So after upgrading to 10.8.2 today, when i right click I have two different 'Preview' entires to open with:

Preview (6.0)
Preview (6.0.1)

I confirmed there are two version, since I can open both and go to about and see each has its own version number.

There is also duplicates of Safari.

You need to rebuild launch services database by running the below command in Terminal.

10.8.2 did the same thing to me.

/System/Library/Frameworks/ApplicationServices.framework/Frameworks/ LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
