Software erfolgreich installiert - bei Bedarf gerne wieder

Review of: Office 2021 Professional Plus

Der Bestellvorgang mit den Infos per Mail funktionierte ohne Probleme. Nach der Deinstallation vom vorinstallierten MS 365 hat alles super geklappt. Installation verlief reibungslos. Mich als Laien hat das fiktive DVD-Laufwerk etwas irritiert, da mein Notebook über kein Laufwerk verfügt. Da hätten ein paar Hinweise und Erklärungen geholfen. Auch die Ablage der Programmkomponenten musste ich erst suchen, sind nur als Verknüpfungen zu finden.

Windows 11 Pro and Office 2021 Professional Plus can be installed together on one PC.

If another version of Office is already installed on the PC, such as a preinstalled copy of Microsoft 365, please uninstall it first. Two versions of Office with the same programs can't run side by side.

Keep the installation file and product key for your previous version of Office in case you need it again later.
