LabVIEW "save for previous version" get stuck and crashes

[DavideBrusamolino02]

Hi everyone,

i'm trying to save a project made with LabVIEW 2020 to LabVIEW 2016 (because i need to use it on a PC that has only LV 2016), but during the conversion it get stuch while converting this vi and if i try to stop or do enything else on LabVIEW it starts not responding and i have to close it by force.

Do you have any idea why this happens? I will attach a screenshot of the vi where it get stuck.

Thank you.

Usually when I try to save a project for a previous version, it's grayed out and I can't even start.

I can't troubleshoot well from a simple error message, but it should of course NOT convert anything that's in the LabVIEW system folder. Did you explicitly add system stuff to the project that should just be in dependencies? Do you use any toolkits?

If project items and dependencies are scattered all over the computer, "save for previous" will create very deep hierarchies that could exceed the capabilities of the file system.

Is this a simple PC project or does it also contain .e.g RT and FPGA, etc.

Is not a project i have made, i just have to convert it to LV 2016 and test if it works.

I have checked and the VI that causes the crash seems not to be called anywhere, that's very strange.

Yes the project uses some toolkits: VISA, IMAQ and GOOP, but the problematic VI is not part of any of these.
