What is LabView load error code 34?

[IMSYSINC]

I'm using the 30 day evaluation version 7. I created a very basic instrument I/O .vi to test the capabilities of the software. The .vi works fine on the development machine, but when I try to open it on a different machine, which has the LabView 7 Reader installed, I get the above error. I'm guessing it's because it is a trial version, but I want to make sure I'm not missing anything.

Thank you.

Jack Remiasz,

Let's see if we can get to the bottom of this. Which operating systems are you running and which VIs are you using? Also if you could include the text of the error message that would be helpful. Thanks!

Hi, I have this problem too. I made a project at LabView and Try it to open at LabView evaluation version 7.1 at player mode. The computer was slower that the computer that I made the project. The message was at popup window: “error code 34.”

Karra,

I believe that the following Knowledge Base entry answers this question:

"LabVIEW Error Code 34 when opening a VI in the LabVIEW Player"

Any VI that we open in the LabVIEW Player must be signed. Error 34 will pop up when we try to run a non-signed VI. We can sign our VIs by using the LabVIEW Professional Development System 7.x and the LabVIEW Player VI Creation Toolkit. Please refer to the link above for more information. Hope that helps!
