Installing 2017 RT after 2022 full version

[gbartlett@prior.com]

Hi all.  We have a existing customer-facing application built with 2017 Labview.  For reasons of backwards compatibility back in 2017 when the application was written, we built this with 32-bit Labview.  Fairly obviously then, it needs the 32-bit LV2017 runtime engine, and we distribute that with the application.

We've had reports from customers who've installed more recent versions of Labview (specifically LV2022, but we have no idea whether it happens on previous versions too) that they could not install the LV2017 runtime.  (See the attached picture of where the installer refuses to go further.)

I did wonder if a more recent runtime would supersede this and allow the application to run anyway, but in fact it doesn't work.  (See the attached picture again.)

I'm not sure what's happening here, or how to fix it.  I would expect applications to possibly have issues with different versions of Windows (MS changing the rules under you is always a possibility!), but as far as I knew, I expected different versions of LV to install side-by-side without problems.

Does anyone have any advice for what we can do about this, please?

Several comments.

• The first set of messages from NI LabVIEW Runtime 2017 SP1 f4 are telling you that the four elements you are trying to install are already installed.  NI does try to make newer components "backward compatible" (for 4-5 years) with earlier releases, so it is possible that the items not installed will still let your software run (because it can use the later drivers).
• I don't understand the second "picture".  "Images" are generally not so helpful.

You might have a working LabVIEW system.  Did you try running LabVIEW 2017 software?  Did you get an Error?  Can you get a good "capture" of the error?  Can you attach the VI that caused the error (it should be the last one mentioned on the Error message)?

That combination of LabVIEW tricked me. That was a post earlier about problem with LabVIEW 2022. 

See this post:

You might need to install VC 2015 to fix the problem.

I've just searched the text from the second picture, and came up with this.  It's exactly the same error message.

We'll go and ask the customer to follow the repair process.
