When I tried "deleting all NI Software off my computer", the only way I could move forward was to reformat the C: drive, reinstall Windows 10, reinstall all of my other software, and reinstall LabVIEW.
As difficult as it is to install (and remove) LabVIEW, attempting to do a "manual" removal through RegEdit is extremely difficult (after 10 years of no problems with Installs and Removals, LabVIEW 2017 caused me two PC Rebuilds until I "got the message" and returned to "Programs and Features" for NI Software removal).
I think I've posted somewhere on the Forum the "Safe" way to remove LabVIEW 2019 (which I've done about a dozen times while trying to build a system with multiple LabVIEWs from LabVIEW 2016 through 2019). You can also find NI's version on the Web.
The message you are getting is a "bug" in NIPM, one that NI knows about and I believe is working to fix. One solution is to do the following:
- Start the Install. When/if you get such an Error Message, cancel just that installation, but attempt to continue with what remains. Go as far as you can until it seems hopeless, then cancel from this pass.
- Repeat the Installation. But this time, do not choose "everything I want". Install one "package" or "driver", and only a few Additional Items. You may (if you are really unlucky) have to do one at a time, but "progress is progress" ...

P.S. -- one of the most challenging aspects of LabVIEW, especially for the beginner, is Installation. I always did the installations for my colleagues, for the Teaching Labs, and for students who came for consults.
