Error running Developer Framework

I had the developer framework running for ages and needed to go and modify some AF variables but when I started the application (OSX), I got this message:

The DeveloperStudioALEOS executable launcher was unable to locate its companion shared library.

I tried downloading and running the latest version for OSX 64 bit and get the same message. I don’t know if it is related but I had eclipse issues with the STM32 dev environment so I had to reinstall that. It looks like the latest developer framework for AF is supposed to be standalone and not require any other libraries. Any thoughts or things I can try to get it running again?

Found this fix (run from the install directory):

***xattr -d ****
