I have had problems trying to load Tracker 5.1.5 6.3.0 / 6.3.2

After starting the installer the following message arrives:
6.3.0 / 6.3.2
Problem running post-install step. Installation may not complete correctly
Error running /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -domain local -domain system -domain user: # The -kill option has been removed because it was dangerous and no longer useful.

Once the install process is finished:
There has been an error.
Error running open ***unknown variable trackerapp***: The files /***unknown, /variable, and /trackerapp*** do not exist.
The application will exit now.

These message came later after I tried to update Tracker but then I got message saying there was a problem with the Xuggle video engine.
