I don't really understand what is happening. Could you please tell us:
Apologies if it was not clear.
Where your Tesseract language files are located (the files are named like 'eng.traineddata' etc)
C:\Program Files\tesseract-ocr\tessdata
The value of your TESSDATA_PREFIX environment variable (it should point to an existing folder)
C:\Program Files\tesseract-ocr\tessdata
The content of the folder pointed by TESSDATA_PREFIX (it should contain the language files)
eng.traineddata , fra.traineddata, deu.traineddata
Your data looks OK.
Additional questions:
Could you post the first lines of the last Audiveris log file?
These log files are located (for Windows) in the folder %APPDATA%\AudiverisLtd\audiveris\log. (I suppose you have used the Windows installer for Audiveris, please correct me if I'm wrong)
More information about log files are available here and there.
This kind of file is key, because it displays important information seen from Audiveris. As an example, here is the beginning of a log file of mine:

As you can see, it displays the values of TESSDATA_PREFIX and of the OCR folder, as seen from Audiveris application. I'm insisting on this, because I'm not familiar at all with the way you launch Audiveris, and especially the role of the Server.js file you posted in a previous message.

The Server.js is to run Auriveris as a batch , by getting the pdfs from the front end.

So, a line is missing in your log file. The line is supposed to be: "OCR folder: ..." Since you have TESSDATA_PREFIX defined, I guess the location pointed to by its value does not exist or is not a directory.
Please post the (Windows) listing of this folder.
Update: The line "OCR folder:..." appears in 5.4-alpha, not in the released 5.3.1
But I just checked in old 5.3.1 code: if the folder exists and is really a directory with the eng.traineddata files and others, it should work. The more I think about it, the more I suspect this spurious location.
The way audiveris sees the location is the problem. C:\Program Files\tesseract-ocr\tessdata/fra.traineddata
so the path is good as defined in the env variable until tessdata, and then audiveris adds / .
Here's the directory screenshot.
These data files are NOT the needed ones.
Here is my own listing:
Notice the sizes of mine vs yours. For example the eng.traineddata file weighs 478KB on your side and 22917KB on mine.
Please download the correct data files, as explained in this section of Audiveris handbook.
Note: I don't think the "/" separator is wrong. This separator is needed and inserted by a call to Path.resolve(location) which is a standard Java method.
Thank you. Yes, it was the files. I did download from the same place previously, but instead of download, i was saving the link , not sure why that was causing the issue. But thank you sir, the issue is resolved
This topic of wrong datafiles is a recurring one... In version 5.4 (not released yet, but you can build it on your own), 4 language datafiles are now pre-located in Audiveris resources folder by the Windows installer.
The same problem can still occur if the user wants to manually add other languages, but it's already a step forward.
I'd like to offer a way to download languages from within the Audiveris application. However, the tessdata target folder (though writable by the Windows installer) may not be writable by the end user, unless I find a way to elevate user priviledges for this. If someone knows how to do this, I'm interested!
I'm using windows and vue.js
Audiveris stderr: Error opening data file C:\Program Files\tesseract-ocr\tessdata/deu.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language 'deu' Error opening data file C:\Program Files\tesseract-ocr\tessdata/eng.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.

Thats the error im getting. Its funny that it was recognizing the env variable i set C:\Program Files\tesseract-ocr\tessdata however , it amends it with a wrong '/' when looking for lang files. where should be doing '\'
Got annoyed with the TESSDATA_PREFIX , so i deleted it and then i created C:\Program Files\tesseract-ocr\tessdata as that seems to be the default directory audiveris looks for as per docs.
here's from the docs which talks about the default https://audiveris.github.io/audiveris/_pages/install/languages/
I have a Server.js setup, with a post
So no matter what i do, I end up with the same error, create the env variable or not. The path is wrong of course, but why is Audiveris doing that?
