# Installation SSRS

#### Download

Der Download erfolgt hier:\
<https://www.microsoft.com/en-us/download/details.aspx?id=100122> (Version 2019)\

#### Wichtige Anmerkung Lizenz-Schlüssel:

Es ist dringend zu empfehlen die SSRS direkt mit dem richtigen Lizenzkey der SQL-Server Installation zu installieren. Dies nachträglich zu ändern ist relativ aufwändig.

Dies kann man ggfs. über folgendes Powershell-Kommando abfragen.
