Why Do I Get Error 20 When I am Trying to Open a VI Written in the Evaluation Version of LabVIEW?



Primary Software:
Primary Software Version: 1.0
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I wrote VIs in the Evaluation Version of LabVIEW, and I saved them in a VI library. When I try to open them in either the Full or Professional Development System, I get Error Code 20: This VI can only be opened in the Evaluation Version of LabVIEW.

Solution:
VIs in the Evaluation Version are limited in capabilities compared to the Full or Professional Development System. If the VI was Saved with Options and Include vi.lib files was checked to save  the VI, you will receive Error Code 20: This VI can only be opened in the Evaluation Version of LabVIEW. The vi.lib is a directory that contains the standard LabVIEW functions.

Some examples of the VIs created in the VI library include Instrument I/O VIs. Before using the VI created in the Evaluation Version, remove the VI library so that LabVIEW may look for the native VIs associated with the Full or Professional Development System.

Developer Zone Example: Removing vi.lib Files from a Hierarchy, Directory, or LLB is an example program that allows the removal of the vi.lib files or files in any specified location from a selected VI library (LLB) or directory.
