I have done all the steps that are listed in the troubleshooting instructions. But it didn't help.
None of the recommendations helped solve the problem. Installation files are needed
Then please contact N.I. Native Access and Installation Support . In case that you need guidance contacting support : How to contact NI Support and How to get in touch with our Customer Care
Give us a clue then - presumably you have clicked Install, then what happens?
Help article is here : Native Access Error: "Path is invalid"
Otherwise : Have you done all the Mac users must do when using N.I. software ? :
ALL NI apps including NTKDaemon must have full disk access. : How to Enable Full Disk Access on macOS and disks must be of correct format : Notes on Network Drives and Disk Formats
Also then please check that iCloud Private Relay has been turned off : Native Access Error Message: "Download failed" (macOS)
Also then do not use Clean My Mac.
And quote Kymeia : if using Sequoia then N.I. apps must be added to the Local Network
It says you need to grant full disk access - which implies you've not done that.
Also, as the original message mentioned an invalid path, what path are you trying to use?
