Yes my libraries are downloaded. Native Access says the paths are invalid. They are on a hard drive that is formatted correctly. My libraries are messed up and I don't know why.
How are your File Preferences defined?
.
As asked by DunedinDragon then please give us a screenshot of your File managements settings in NA.
Also then what is your exact OS version ?
Did you also give ALL NI apps including NTKDaemon full disk access ? : How to Enable Full Disk Access on macOS
and are you using latest version of Native Access for your OS ?
"Add Product" is a "manual" term - anything exposed in your NA listings with this button showing - is designed to be authorized by Native Access - but must to be downloaded manually and then placed manually.
I have several of these old school libraries showing - this is due to a new (now longstanding) bug in Native Access (from about 6 months ago now) that suddenly made these super old things to show by default - where they never did before.
All you do is ignore them OR find the old product on the Internet, download and place it and then click Add Product and point NA to the library location.
