Installing earlier releases of the DataStax Distribution of Apache Cassandra 3.x for Windows

Steps for installing the same version as other nodes in your cluster.

DataStax no longer provides the DataStax Community version of Apache Cassandra™ or the DataStax Distribution of Apache Cassandra. See DataStax support for Apache Cassandra.
To download and install the latest version of open-source Cassandra, see https://cassandra.apache.org/.

Download the previous version you want from Apache Cassandra and follow the install instructions for that version.
