I regularly get an error similar to this:

JInstaller: :Install: File does not exist /*******/public_html/dev/tmp/install_5e834b10a9f88/en-GB.plg_system_kou_address_mapper.ini

Here is my XML

    <language tag="en-GB">en-GB.plg_system_kou_address_mapper.ini</language>
    <language tag="en-GB">en-GB.plg_system_kou_address_mapper.sys.ini</language>

I check and I see both files exist. I copy and paste the files names to make sure there are no errors. The .sys file seems to load correctly. Here is the name copied and pasted:


The location is the same as the .sys version which is:


This happens a lot and I find it really hard to understand what the issue is. The file exists, and when I check my zip file it is there. Does anyone have a clue as to what I'm doing wrong as this happens a lot and I haven't got a very reliable methodology to check for errors other than checking spelling.

Your file structure doesn't match the manifest file. Currently the manifest looks for language files in the root directory of your package.

You can add folder attribute with path to language files to <languages> tag:

<languages folder="language/en-GB">
    <language tag="en-GB">en-GB.plg_system_kou_address_mapper.ini</language>
    <language tag="en-GB">en-GB.plg_system_kou_address_mapper.sys.ini</language>

Or prepend the path to each <language> tag:

    <language tag="en-GB">language/en-GB/en-GB.plg_system_kou_address_mapper.ini</language>
    <language tag="en-GB">language/en-GB/en-GB.plg_system_kou_address_mapper.sys.ini</language>

Or move language files to root directory.

  • Ah ha! That's amazing. It's been over a year I've been having similar problems. Why does the .sys version work? I can't believe I have got any of my plugins/modules working without this knowledge! Thanks so much

    As far as I can tell, the .sys file does not get installed either but it does get loaded from temporary folder during installation, provided the file structure follows a certain convention (i.e. language/en-GB).

  • Ah, I thought the convention carried through. I must have read that somewhere. Thank you.
