Error 7 occurred at Open VI Reference with Application Builder

Question

Using Labview 5.1, I am building an application where all the vi's are placed in a single .LLB file. I have one top level vi (with sub-vi's), and one vi that is opened by the Open VI command. The program runs fine with labview installed. I want to make an executable file. I select the top level vi and select the vi that is opened by the Open VI command as a dynamically loaded file. I get an error when I attempt to build the file.
"Error 7 occured at Open VI Reference in Dist Build LLB Image.vi -> Dist Build App Image.vi -> Build application.vi"

Answer 1

Dear Sir;
There are two things that are good to try:
First, create the application in a folder that is closer to the root directory (e.g., c:\myApp). There is a limit to the length (or depth) of the path name to your application's target directory, so, if you are choosing a too long path you might get an error.
Second: The Application Builder reads certain information from the VI in order to determine how to build the executable. To avoid possible errors, either in the build process or in the built executable, make sure the VIs are LabVIEW 5.1 VIs. You can convert your VIs to LabVIEW 5.1 VIs by using the Mass Compile feature (File >> Mass Compile) in LabVIEW before you build your executable. The Mass Compile feature will allow you to select either a directory or a LabVIEW
.llb file to compile.
