Project won't open

[NiSwIsRubbish]

Hi,

Can I get some help please?

I've got a new install here of LV 2023, Q3. Also, a project written in an unknown version by an Engineer who is no longer available.

I can't make the project open up, it just gives the error "labview (hex 0x465) file version is later than the current labview version". No hint as to what version is needed, no way to proceed or what to do, nothing. I've gone into help, and looked for upgrades, and there is nothing.

Surely the exact same version number isn't necessary...!?

Can anyone advise, as currently this is where we are, having spent hundreds of pounds on a program, it is useless, as it cannot accomplish the very first task it is asked to do.

Thanks

Oh, I also cannot raise a support ticket, as that takes me to here...

The version of a .lvproj is written all the way at the top of the XML.So open the .lvproj in notepad, and check it yourself:

<?xml version='1.0' encoding='UTF-8'?>
<Project Type="Project" LVVersion="23008000">

However, normally you should indeed be able to open the project in newer versions. And indeed, when your version is older, you should get a popup mentioning the newer version.

So I suspect you're file got damaged (corrupt) or you're opening something that isn't a LabVIEW project at all. That's basically the same as far as LabVIEW is concerned.

We'd need files or at least screenshots to help with that.

I just got this too with my crashes.

Hopefully it's just a temporary glitch in the interweb. But it might be caused by an oversight in changes... 

But I don't think that will get you a ticket. It's mostly used for statistics. In 25 years I never got any response on crash reports.

I think the send crash is searched in the archive for similar crashes and solutions. I won't expect too much of this one though.

I reported this here: LabVIEW crash reports page fails - NI Community

Thanks for the help, much appreciated.

Looking at the xml, I have the following in the first three lines:

<?xml version='1.0' encoding='UTF-8'?>
<Project Type="Project" LVVersion="24008000">
<Item Name="My Computer" Type="My Computer">

So is this 2024? No idea how to obtain this if we were sold 2023...?

Trying to open this project in LV gives me this...

Thanks again

The .lvproj seems to be LV24.

That might be the expected response.

You could try to open an individual VI (bypassing the project). But usually they would match version.

You can obviously buy LV24... I assume you want to avoid that.

I think you'd be OK, maybe even within what's legal, to install the LV24 (or 25) Community Edition, iff you use it only to save back the project.

Actually, in 24 an up, you can set the project to save as earlier version. That's a lot easier that "save to previous".

Alternatively, you can ask online to convert, but obviously that means trusting someone with your code.

Hopefully your code lives in a source code control system. That should give you insight in when the project changed to LV24. And of course that gives you choices to revert.

Even if you choose to save back, I'd definitely try to get to the bottom of it, to satisfy my curiosity and learn. Without SCC, that search would end pretty quickly though.
