Issue Details

I want to use a Packed Project Library (PPL, *.lvlibp) in a different version of LabVIEW than the version used to build the library.

Solution

PPLs compiled in LabVIEW 2016 or earlier cannot 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 the 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.

 

  1. Open the Packed Library build specification properties.
  2. Select Advanced.
  3. Enable Allow future versions of LabVIEW to load this packed library. (This option is enabled by default).
  4. Build the Packed Project Library.



 

Additional Information

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