An error occurred loading VI '<Packed_Library.lvlibp: <VI Name>'

Solution

This issue occurs when the packed library is built and used under different system. Try to build the packed library under Real-Time target and add the built packed library under Real-Time target as shown below:

not loaded issue solution

To avoid this issue, if you build the packed library under Windows system, you should add the built packed library under Windows system. Similarly, if you want to use the packed library under Real-Time target, the packed library is required to build under Real-Time system.
