El Capitan: Cannot open the application "app name" because it may be damaged or incomplete

Came across this several times. After you initially upgrade to El Capitan 10.11.2, after logging into my main account (admin), I was not able to open applications and received the following error:

"Cannot open the application name"app"because it may be damaged or incomplete."

I couldn't open "Activity Monitor", "System Preferences", "Finder" or anything (provided, App Store or other system). The icons will revert to the default application icon. Other users have no problem with the same apps.

After the panic, I found a solution: go to another admin account, delete the old user account, and then add it again. This version corrects the problem of this user; It apparently rebuilt the user for that user identity information, while leaving their home folder (and preferences, documents, key rings, etc.) only. iCloud information must be re-entered, but it is trivial. Once the user delete and add, I was able to run these applications.

When I upgraded to 10.11.3, it is the same thing, but to 3 accounts. I managed to solve this problem through the guest account - that is, I was still able to authenticate as an administrator, but I could not open a session and run anything.

El Capitan removed permissions repair; I think it can be done in the recovery console, but I shouldn't do that.

No idea why this continues to be?

Generally to searching for the above error message is specific to applications from the App Store or other, not about things like "Activity Monitor" and "System Preferences."

You now have this problem?
