Rekordbox fails to update, happening for years now

Windows 10 PC here, It's been years now that I've seen the Rekordbox updater stall out when updating.  

It usually gets stuck after un-installing old Rekordbox / attempting to launch new version. The background process just gets stuck running. You have to force quit or restart, you launch Rekordbox and it's back on the previous version. 

Any workarounds for this? It's been happening to me for years now, how is their PC updater such hot garbage for so long? It fails to update more often that it succeeds. I'm on a very powerful custom built PC, this is not an issue with disk space or low resources, this is a Pioneer has poor app code issue.
