After double-click the Admin_Tool_v2.1.app (has just genericic icon)
I get the following message:

"Admin_Tool_v2.1 cannot be opened because of a problem.
Check with the developer to make sure Admin_Tool_v2.1 works with this version of OS X. You may need to reinstall the application. Be sure to install any available updates for the application and OS X.


Click Report to see more detailed information and send a report to Apple."

But Admin_Tool_v2.0.app works great!

Tested on iMac and MacBook, booth with same result.

Where is the problem?
