FWIW,  there have been a couple of occasions that I can recall where this
worked for me,  too.  A program would just start acting weird,  with no
apparent explanation for its behavior,  or it wouldn't work at all,  either
freezing up or dropping back to a command prompt with no further action. 
Re-installing it helped to cure the problem.

Only once or twice over a lot of years,  but yeah,  it's happened.

Good thing I keep the distribution archives around.  :-)
