ScreenSaverEngine Error Message

I have the bottom-left Active Screen Corner on my iMac to Start Screen Saver when I move the pointer into it.

The problem is, when I do that, an error message pops up saying:

You are opening the application "ScreenSaverEngine" for the first time. Are you sure you want to open this application? This application is in a folder named "Resources." To see the application in the Finder without opening it, click Show Application.

When I click Open nothing happens. When I click Open again, the error message goes again. But the screensaver never starts.

Anyone know what's going on?

Restarting my iMac solved the problem, for now. It's a weird error message to get though. Very Microsoft and not at all what I'd expect from Apple.

I just started getting this and the answer seem to be in the Permissions.

I simply did a get info and changed all Permissions to allow all to Read and Write.

Cheers,

When you say "all Permissions" what do you mean? All permissions for everything on your hard drive?

I've been annoyed by this bug for 2 years now,

When is Apple going to step up and fix this?

I realize this is an old thread, but I am having the same problem and I found the following answer in an archived discussion. The problem is, I am not quite sure how to use Terminal and I tried following the instructions but couldn't figure it out. Any help out there?

Got the same problem here.
Seems I got rid of it by updating my LaunchServices database :

1) Open the Terminal, and log in with an admin account (by using su and/or sudo for example) if your current OSX account does not have admin privileges.

2) Go to the LaunchServices.framework' Support directory :
*cd /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fra mework/Support*
+(Note: in previous OSX versions, it was a subframework of ApplicationServices and not CoreServices, the path has changed since)+

3) Use the "lsregister" commande line tool found in this directory to do a rescan/rebuild of your LaunchServices database. You can e.g. update your whole database with this command :
*./lsregister -r -apps local,system,user*
+(Or you can specify the path to the ScreenSaverEngine.app itself directly as a parameter)+

------

After the LaunchService database has been rebuild, you should be good with ScreenSaverEngine (you can use an active corner to launch it immediately and check if the fix worked).
