EN; ...) <- here should be the list of installed modules, starting with WORLD. It is empty, that's why it does not update.
It looks like the last, but not the least setup stages failed to execute.
If you can find latest DCS-related "Setup Log #xxx.txt" in your Temp folder, please post it, we'll try to figure out the cause.
Meanwhile, you may try to repair your install manually. You should run admin command line in the game install dir and do a couple of commands, in fact, replicating those steps of the setup.exe:
bin\DCS_updater.exe init EN
bin\DCS_updater.exe install WORLD
If you installed any additional modules, you'll have to "install" those as well.
