LaunchServicesError error 0 - simulator

[Alan Stenhouse]

After installing LC 6.7.8 RC1 and testing an app under it, I now find that opening the same app in LC 6.7.6 and attempting to run it on the simulator 8.2 results in the error

“Unable to start simulation: The operation couldn’t be completed. (LaunchServicesError error 0.)”

The app previously ran fine. And it also seems to run ok under 6.7.8 RC1.

Anyone come across this before??  If interested some relevant messages from the system.log are below.

OSX 10.9.5

cheers

Alan
