When I downloaded an application (e.g. RubyMine) and transfered it to the Applications folder, the application wont start (nothing happens). It is not limited to the Applications folder, it appears for every directory I unpack the downloaded app (out of the .dmg).
When I type
open RubyMine.app in the Terminal, I get:
LSOpenURLsWithRole() failed with error -10658 for the file /Applications/RubyMine.app.
And it happens with more apps then only RubyMine.
What can I do about this? At the beginning i was asked to allow the startup of the downloaded app, but now this appears every time.
