Why am I seeing “An error occurred while trying to run the script.” in the UI Automation instrument?

Question

When I try to run a UI Automation script on iOS 5 devices I am getting the following error:

\"An error occurred while trying to run the script.\"

Answer 1

I would try closing xcode and starting the automation script without xcode running. I had an issue where the process was attached to xcode, when I attempted to run from instruments, xcode got stuck on a breakpoint/crash and I couldn't proceed.

The solution I'm proposing is run Instruments independent of xcode.
