No That's not it, most of the time Gatekeeper warns you can not run this app, because of security reasons. Ctrl-click does the trick in those cases.
With the REQW app, it says it is damaged, and I have to delete it. No other option.
Strange thing is the link is a zip file, but all I can see is an .app file...:scratch:
Yep. I'm the one who posted the "problem" with Mountain Lion. The error message ("Damaged File") threw me. Once you relax the gatekeeper settings, everything works like a champ. The files are just fine.
I personally don't think turning off application signature checking, an important security feature of the OS, is a good solution.
What you *can* do is launch the Jar directly. Right (or control) click the app, select show package contents, navigate to the Java folder, and right click the RoomEQ_Wizard_obf.jar file and select open (you will be prompted the first time you run it, and after that you can just double-click it.)
It's not a permanent solution, but I also don't run the program very often.
