Hi nikki7,

 

Are you using a non-english operating system? If you are, then the KnowledgeBase article I included below should be helpful. I hope this helps!

I came to the same error message when installing LabVIEW using ni-package manager 2023 Q4. 

As the message was the same I post in this thread as well.

For my case the cure was to run ni package manger as administrator.

instead of launching the installer (ni package manager in this case) from the start menu with a left click - as you do mostly, right-click and among the choices are "run as administrator".

 

Disclaimer: Now - normally it is unsafe to install as administrator and if you do it implies you fully trust the source of the program.
