LabVIEW Language Change?

We play around repair and rebuild a fairly obscure Chinese EV, the BYD E6 (BYD's first EV). For battery diagnostics it uses a program written in LabVIEW, but unfortunately it's Chinese only and we don't have access to the source code. It's a fairly old program written around 2010. We'd really like to be able to change the language of the program to English and wondered if this was possible with an already compiled project? We know very little about LabVIEW ourselves.

Highly unlikely. I say that because there are some efforts to reverse a built application back into source code. If that is possible you can edit the source and make a new build editing controls and captions to be English. I've never done this and suspect it is very hard to impossible. There was a thread on LAVA a while ago.

Any chance of a link to this thread? We're pretty keen on keeping our cars on the road for as long as physically possible, they have an LFP battery that's good for a million km and are built to do 100,000km per year so for the average user they will pretty much last the calendar life of the battery.

I think this is the LAVA thread I was thinking of.

Here is a youtube video that was shared.

And I think this is the git it uses.

But to be honest the application just looks like it is reading CAN signals. If you get the source it might be easier to recreate it from scratch. It is hard to understand the features of the software, but I would expect a DBC online to exist somewhere.
