First, You should post this question in the LabVIEW Board, not the PXI Board as it has nothing to do with PXI. You may be trying to open a VI to use with your PXI device, but the question is a LV question, not a PXI question. This Board gets far less activity than the LV Board.
Second, The error message indicates that the VI is not in memory. That part seems clear enough. The next line tells you what to do if you want to LOAD a VI into memory. I am guessing that you want to load the Strain Samples VI. To do that you must use a complete path, not just the VI name. Look at the help for the File Path functions for more information.
