- Microsoft Dynamics 365 v9.0 on-premise doesn’t have support for Windows Server 2019 or SQL Server 2017, but it does have an ISO installation file.
- Microsoft Dynamics 365 v9.1 on-premise has support for Server 2019 and SQL 2017 and later, but it does not have an ISO installation file, and it is only released as an upgrade to v9.0.
Many thanks
