I've been getting this message, too, every time I run up the app, but it never installs anything, because next time whether I had clicked on it or not, it asks me to install it all over again, and the next time, and the next time. It won't install, and I get no error messages that it has failed to install. On top of that, my update subscription expired on 4th March 2020, as I also get reminded every time I've run up the app since then. It gets old really, really quickly!

Edit: Even running up XDP as administrator doesn't get it to install properly, as I just tried that in the vain hope it would stop pestering me to re-install it.
