Welcome to the forum.
It depends whether you are using a mySQL database with Kodi, or an sqLite database with Kodi.
Your photos appear to show:
1. the xMySql plugin in VC, and then
2. the Xsql plugin in VC (which is for peope who are using an sqLite database)
You should only be using one of those plugins, not both.
Use the xMySql plugin only if you are using a mySQL database in Kodi. Otherwise, you should use the xSql plugin to generate your payload xml.
In the xSql plugin screenshot that you posted, the file paths to the various databases are green. That indicates that VC has found those Kodi databases.
I suspect that means that on your Raspberry Pi you're actually using sqLite, not mySql, to store your media library info. (Though I'm not sure. Maybe that database will still exist, even if you're not actively using it.)
HOWEVER: You will probably still get an error, because you have incorrectly changed the "Output folder" path.
That file path should be left as:
.\XbmcPayloads
If you look in your VoxCommando folder, you'll see a subfolder there called "XbmcPayloads".
The output folder path is the folder where VoxCommando will store your payloadXML files. You should not change that file path to a folder on your Raspberry Pi.
Try fixing the file path in the xSql plugin, and then click "save and generate".
If you're still getting error messages, you'll need to post a log so that we can see more details.
