Recently upgraded my Mac OSX to 10.9. Now whenever I create a runtime solution in FMPA 12 I get an error message 'This file is locked or in use'. It is 'info.plist' that is 'locked or in use'. I click 'OK' and the the runtime creation completes with no further messages.
However, when I execute the runtime, I get the error:
"you can't open the application xxxx because it may be damaged or incomplete.
This is reproducible.
Never had this issue in OSX 10.7.
Is there something I should know about 10.9 and FMPA 12?
