Old software version issues: NI-VISA 14.0.1 vs windows 10

[VinnyAstro]

Hi!

Here is the situation:

An old project appeared on my desk recently, a customer reset his computer and installed Windows 10, and re-installed the software which doesn't work anymore.

Among the two main issues, one of them appear is VISA Open.vi (error -1073807202) which apparently could come from the NI-VISA drivers.

In the installer build specification I saw that NI-VISA runtime isn't checked in the "additional Installers" section.

Problems:

The software was developped under LV11 (so I suppose a LV runtime engime from 2011 as well) which means a NI-VISA version from 5.1.1 to 14.0.1 according to this page 

But NI-VISA 14.0.1 doesn't seem to be supported on Windows 10

Is it really the case? Hasn't been tested? Or just that the website hasn't been updated since then?

Otherwise, I'm currently working on LV19, should I start working on releasing an upgraded version to LV RT 19?

Thank you in advance for your help.

It probably has not officially been tested.  NI isn't going to keep supporting all old versions of LabVIEW going back to versions that written and released before the newer operating systems were created.  It is possible that VISA would still work, and if you follow the forums, you'll see sometimes people have success running older software on newer operating systems, but there are no guarantees.

So you can try to run it, but the best solution is to proceed with what you've started and to update your VI's to a recent version of LabVIEW.

Yeah to be honnest, I would rather wipe this code and start fresh, but unfortunately I can't.

I'll try running it on windows 10, and update here my results that could eventually help someone later on.

But in any case I will probably have to update all VIs to a more recent version yup. Hope it will go smoothly 🤞

Any advice on a specific procedure to follow is more than welcome, never done that before.

Make a backup copy of your current code and store it away somewhere else.  That way you don't accidentally corrupt something if VI's get cross-linked between versions.

Then just open your project up in LV19.  See what's broken or missing.  You might find that there are other toolkits or libraries you'll need to download and install into LV19.  Then work through and fix any broken VI's and test out the operation.

I really don't expect you'll have any major issues with the LV11 to LV19 upgrading.

Ok thanks.

I'm working with svn anyway, so I shouldn't have backup problems.

Given what the customer sent me, the rror message where pointing out these NI-VISA drivers missing and when I opend the project (with LV19) and went in the build spec of the installer, all additional installers where for my current version (RT19 + NI-VISA20) but NI VISA wasn't checked.
So I think I'll just try to do a mass compile, re-build the installer and see how it goes.
