This is the biggest problem Adobe has. They laid off a couple of the wrong people. They should have kept a couple of the OS gurus.
I've had to manually to into the registry to link photoshop, indesign, and illustrator files. Who knows what the links are with droplets. They should just work!
But uninstalling all the apps, running a goofy little utility that never should have been created in the first place, then reinstalling all the apps is NOT the signature of a class operation.
