Labview version 2020 to version 2021

[ALBO3012]

Hi,

I have a LV program which works fine when I make a build with LV20. Same with LV19 and so on.

I can also run the main.vi in LV21 and it works fine.

But to stay updated I want to make a build in LV21.

When I do this I get error 99. See attached picture.

Can anyone help me?

Please keep in mind that I am new to LV.

Hi Albo,

did you debug your VI to find the offending function?

Which kind of files do you try to access?

Does the error occur on a Read or on a Write function?

Are you working with some Datalog files?

Mind to attach the VI where that error occurs? (Please attach for LV2020 or older, not for LV2021…)

Hi GerdW,

Problem solved.

My LV program was using two example VI's located in the LV20 examples folder.

When building with LV21 these VI's is not included in the build. I copied and moved the VI's to a suited location in the project folder.

Thank you for taking the time to reply to my question.

Best regards,

ALBO

Copying them into your project and using them is the best way to handle this.  I'm not exactly clear on whether you did move them or not, but I wouldn't move them, though.

Hi Bill,

Yes I have copied them into my own project. Now it is working fine in LV21.
