I installed the Debugging Symbols, but the engine won't recognize them

I have a project running on 4.12 which is crashing. The crash reporter tells me that “You do not have any debugging symbols required to display the callstack for this crash.”

However, I already have installed the Debugging symbols for 4.12.

I can access the Minidump files, but I’d like to be able to skip that step and see the error of my ways in the crash reporter.

Any help?
