Two versions of eM Client

Guys, I seem to have TWO versions (intances) of eM installed on my device: one called “em Client” the other"eM Client for Windows Store". Which one should I use?

What version is each one? On Windows click on the stack of three horizontal lines at the top left, then Help > About. My installation is showing version 10.1.4588

I seem to have TWO versions (intances) of eM installed on my device: one called “em Client” the other"eM Client for Windows Store.

If you originally downloaded and activated eM Client “via the eM Client website”, then you can uninstall the Windows Store version.

The eM Client website versions are usually also later versions than the Windows store versions.
