This is a little bit of an odd one for me, using LV 2014 I have a program that I am trying to build an executable from. I go through all the usual, select main files, attached files etc. That all works fine, I can build the application and it runs as normal.
However as soon as the build is completed when the name of the application appears in the bottom of my project it is given a ? in a blue circle. Upon trying to reopen the application builder I am greeted with:
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>
Obviously the problem here is that it is trying to call something from somewhere that doesn't exist, but I am not entirely sure on how to resolve this.

But they both deal with missing files from within the application itself not from building the application. And the ability to build correctly the first time is also confusing the matter. Any help is appreciated, this is not a major issue for now considering I can simply delete the build and create another one but it would be nice to resolve.

OK, well it turns out I should have followed the old adage of turn it off and on again.
After leaving for the weekend and shutting everything down I come back today to find that it is all working as expected again. I'm not sure why LabVIEW would point to a blank path and then update itself on shutdown or what is going on at all but hte problem is solved so thats one less issues to deal with.
Thanks for the help anyway Mike.
