Error 1059 occurred at Get LV Class Default Value.vi

[SeanJ]

Hi,

I want to build an llb using a previous installer in a project.

There is a '?' beside the installer. When I double click the installer I get the following message:

Error 1059 occurred at Get LV Class Default Value.vi

Possible reason(s):

LabVIEW:  Unexpected file type.

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>

Does anyone know why I am getting this error and how to resolve it?

Thanks,

Sean

It looks like you do not have all the VIs defined in your system.

I would use project and bring up that particuliar VI and see what the error list shows up. One thing be careful abl=out classes. I have noticed times when it is erring out (class methods are showing errors), I shutdown labview, and rebooted the machine. After that, the errors disappear.
