I've had the same issue with a version 15 (cumulative update 03) installation - it was an issue with the executables .. an install of cumulative update 10 of v15 resolved the issue (with zero code changes to the app). Microsoft didn't publish (in the list of fixes) anything re this issue however their internal notes did have this logged as an issue that they resolved (I believe they only publish info re the fixes that are logged by the community (anything they find themselves they fix but don't announce)).
Update to the latest cumulative update and try your apps again
