LabView cannot load lvclass because it was built in a previous version or for a different target or operating system

[jncuevas]

Hello,

I am currently trying to clean up some code, including replacing references to a coworker's network drive with references to the same files on the local computer.
I have copied the files exactly as they are on the network, and verified that I can open them in LabVIEW 21.
However when I try to right-click in the lvproj and replace the some of the classes I get this message, and none of those reasons are true.
"LabView cannot load lvclass because it was built in a previous version or for a different target or operating system"
Any ideas on how to troubleshoot this or work around it?   The help would be greatly appreciated.

The fact that it claims to be "built" makes me think this class is in a PPL.  If not that, I don't think there is the capability to save a class to lock it into a version like saving a VI with block diagrams removed.

Thank you for the reply.  The class is not in a PPL.

I was able to replace the classes by disconnecting the network from my computer and turning off the wifi.  Then when I opened the project I pointed it to the local copies.
I don't think that explains the error message that LabVIEW gave me, but it got me what I needed.
