Re #13193

Changes:
  - Removes unused languages that bloated the package
  - Moved check for running application to after the install
    directory request so that it checks for the correct path
  - Moved the uninstall of the previous version to just before
    installing the new one so that we only uninstall if we are
    overwriting in the same location.
  - Shows progress during uninstall of the old version rather than
    being silent.
