Invalid protected directory: '[directory full path]'. Protected directories should begin with a target root directory and end in a slash, e.g., [Program Files (32-bit)]\\path\\. Default protected directories will be used.

Why does this error occur?

Package Builder uses the protected directories file, located in '[LocalAppData]\National Instruments\NI Package Builder\ProtectedDirectories.txt'. An invalid directory was detected in this file, and the default protected directories will be used.

How do I resolve this error?

Open the 'Protected Directories.txt' protected directories file and verify that all paths are formatted correctly. Paths should begin with a target root directory and end in a slash, e.g., [Program Files (32-bit)]\\path\\.
