Okay, so I recently moved to an SSD (that was fun), and now two programs are broken and I can't get them to install again.

I've tried removing and purging both programs, and then reinstalling them, but it hasn't worked and at this point, both programs say they're not installed, but still exist.

Running "dropbox" in terminal brings up the usual dialogues, and running "steam" in terminal brings of a window that says it can't find its data.

Is there any way I can locate what's remaining of these programs to finish removing them completely?
