Issue Details

Can a packed project library (PPL) be used in different versions of LabVIEW than the one it was built in?

Solution

PPLs compiled in LabVIEW 2016 or earlier can not be opened using other versions of LabVIEW. For example, if you try to use LabVIEW 2016 to open a PPL that was compiled in LabVIEW 2011, you will get following error message:

LabVIEW: (Hex 0x623) You cannot open a packed library saved in a version earlier than the current version of LabVIEW.



Since LabVIEW 2017 you can compile a packed project library to be also used with newer versions of LabVIEW. In the build specification properties choose Advanced in the sidebar and enable the option Allow future versions of LabVIEW to load this packed library. This option is enabled by default.


 

Additional Information

Since LabVIEW 2017 you can also enable backward compatibility for applications, shared libraries and .NET assemblies .
