Opening Build Specification - Error 7 occurred at Get LV Class Default Value.vi

[Cy.Rybicki]

I recently ported my project to a new PC. Everything seems to run fine uncompiled, and I am able to build an executable without issue. However, my build specification shows up in the project explorer with question mark next to it. When I try to build again or edit the properties I get a popup with the information below:

Error 7 occurred at Get LV Class Default Value.vi

Possible reason(s):

LabVIEW: File not found. The file might be in a different location or deleted. Use the command prompt or the file explorer to verify that the path is correct.
=========================
NI-488: Nonexistent GPIB interface.

Complete call chain:
Get LV Class Default Value.vi
AB_UI_Initialize_Framework.vi
AB_UI_FRAMEWORK.vi
AB_Item_OnDoProperties.vi
AB_Item_OnDoProperties.vi.ProxyCaller

LabVIEW attempted to load the class at this path:
<Empty Path>

I've seen messages from people getting the same error when trying to run a compiled executable, but mine actually runs fine. I am just unable to open the build specification to rebuild or edit its properties.

Hi,

In order to determine where this error may be coming from, it would be a good idea to get some more information about your application.

Are you using a Real-Time operating system or the Report Generation Toolkit?

This application is for a Windows machine, and I am not using the Report Generation Toolkit. However, I shut down my computer last night and when I booted it up this morning my Build Specification now opens fine and I am able to edit it. My only thought as to why it occured in the first place is that I had added several files to user.lib and instr.lib and restarted LabVIEW, but it appears that it required my computer to be restarted as well.

It is very possible that the computer needed to be restarted to complete the configuration changes made to the new PC. I am glad you were able to resolve the issue!
