Q: I can't seem to download and run iTunes 12.0.1.26 on my laptop computer.  It keeps telling me to run installer over and over with no change.

I'm trying to download and install iTunes v12.0.1.26 onto my personal laptop computer.  It will not complete the installation and keeps advising me to run installer over and over.  I had previously uninstalled an earlier version of iTunes (along with Bonjour - which I didn't realize went with iTunes).  I have been unable to locate or recover the Bonjour file so I can't even test the theory of whether this is causing me this grief.  Any advice or assistance in uploading iTunes would be appreciated.
