Anybody else having problems with Mountain Lion restrictions on unknown applications?

After upgrading to the new Mountain Lion OS X 10.8 i can't open an application I already had downloaded that worked on the previous OS X Lion.

It came up with a message saying it wouldn't open because of an unknown developer, and I read you can get around it by right click or option click and open.

When I tried this it didn't come up with a message saying it wouldn't open, but the application still didn't open. Anyone come across this problem and figure out how to fix it?

iMac, OS X Mountain Lion

Go to your System Preferences / Security & Privacy, and change the bottom button to allow from anywhere.

See if that works for you.

You can fix this by going to sys preferences under security you have the gatekeeper options.

Search google for a fuller explanation.

If you open System Preferences>Security & Privacy. Under the General tab choose to Allow Applications downloaded from anywhere.

Now you should be able to launch the application.

A couple caveats:

I assume the app in question is one you used before and is from a know developer that you trust.

It's probably a good idea to restore the Allow Downloads setting back to one of the two more restrictive setttings.
