I am trying to use a labview program written on labview 6.1 on labview 7.1.

Hi,

I am trying to run a program written on LabView 6.1 on Labview 7.1. I haven't really worked with labview much. It gives me an error that it cannot convert the program to a higher version because it is missing a block diagram. I was wondering if there is an easy way to fix it?

Thanks,

Kalina

No fix! 😞

Once a VI is saved without block diagram, it can no longer be edited or upgraded. You would need to find the original code that still contains the block diagram.

For this reason, it is usually not recommended to remove block diagrams. If your VI contains proprietary code that needs to remain secret, the diagram can be passworded. In this case, upgrading is still possible.

Hi Kalina,

altenbach already gave you the correct answer and I am really sorry there is not much we can do at this point. However, if you have any other problems upgrading VIs from one LabVIEW versions to another, feel free to contact us. Simply make sure you have the block diagrams (i.e. the brain of your programs). As a general rule, it is good to mass compile your directory of old VIs, so that they are properly updated to the new version and all subVIs (if any) are relinked. To mass compile, click on Tools»Advanced»Mass Compile.

Hope that helps!
