Importing LabVIEW version 7 or prior .bld Files from Application Builder into Later Versions of LabVIEW

Issue Details

I used LabVIEW 7.1 in the past to build executables or dlls from my application. The LabVIEW 7.1 Application Builder saved the build settings in a .bld file.

I then upgraded my application to a newer LabVIEW version and I would like to use the same Application Builder settings: how can I import .bld files in LabVIEW 8.x and later?


In LabVIEW 8.x and later, the LabVIEW Application Builder is integrated into the Project Explorer window. You can use Build Specifications in the Project Explorer window to create build specifications for and build stand-alone applications (EXEs), shared libraries (DLLs), zip files and installers. Build specifications are equivalent to .bld files in previous versions of the Application Builder.

You can convert a .bld file into a build specification in a new project. You need to follow these steps:
  1. Select Tools»Convert Build Script... to access Convert Build Script Dialog Box
  2. Navigate to and select the .bld file to convert.
  3. Navigate to the LabVIEW project (.lvprj) file to create
LabVIEW uses the .bld file to create a project that contains the source files and build specifications.

Additional Information

Convert Build Script functionality was removed in LabVIEW 2016 and later.

If you need to import .bld files in LabVIEW 2016 or later, you should use an intermediate LabVIEW version (up to 2015 SP1) to convert the .bld file in a LabVIEW project (as explained before). Then, the LabVIEW project can be opened in LabVIEW 2016 or later.
