Error: Need to reinstall Neo4j Browser

Just downloaded Neo4j Desktop 1.6.1.
Created a new DB: it finished without errors
Then try to open Bloom

Graph App 'Neo4j Bloom' can't be opened. See logs for more info (Developer menu in menu bar). Re-installing the app might resolve the issue.

Nothing is reported on any log.

I deleted everything about Neo4j, reinstalled Desktop, but the error persists.
