The problem started when I decided to uninstall Office 2013. I noticed InfoPath 2013 had disappeared a few weeks later when I needed to use it.
No problems I thought - I downloaded InfoPath 2013 from the O365 Portal (Other Installs - infopath_4753-1001_x86_en-us.exe).
However - every install attempt resulted in "Microsoft InfoPath 2013 Encountered an error during setup". Install bar gets to near end and reverses.
So - much googling - many false leads - etc etc. eventually resorted to removing all office applications using O15-ctrremove.cab.
Tried installing InfoPath 2013 first - same error. Ran the remove office app O15-ctrremove.cab again. Restart.
Re installed Microsoft Office 365 ProPlus - another nightmare but eventually got it all working and authenticating properly.
Now I'm stuck with not being able to reinstall SharePoint Designer 2013 (from O365 Portal) and InfoPath 2013.
