I was able to resolve this in an imperfect way.
I went to NI Package Manager and selected Repair. I think I initially chose to repair only VIPM but NI gave me the option to select a bunch more software, I accepted all.
At some point during the repair, VIPM was coming up nicely.
At the end of the repair, however, I was only able to run VIPM from the file location, not using the shortcut. The shortcut only runs "VIPM File Handler" which doesn't even bring up a window, it just shows up in taskbar.
I hope this "solution" can help someone in a similar situation.
