Hi,

ich wollte gerade das Update von MM auf 5.43 (nur Client) installieren.
Leider schlägt das unter Win 11 25H2 fehl, weil Smart App Control von Windows das Programm blockt, da es angeblich nicht aus einer vertrauensvollen Quelle stammt.
Hat jemand das gleiche Problem?
Hat schon jemand eine Lösung ohne Smart App Control komplett zu deaktivieren?

Gruß Klaus

Can you send a screenshot of the message please?

The installer should be signed.

Please extract the file from the zip - right click the installer file and see if you have an "Unblock" button.

This looks like the block Windows sometimes have when downloading installers from the internet.

nein, es gibt kein Menüpunkt "entblocken"

Ich habe den Client auch nochmals deinstalliert und neu installiert:

MM 5.42 geht, MM 5.43 geht nicht
