Prerequisites

To use DeployR, the following components are required.

• StifleR Server 2.14 and StifleR Dashboard 2.14. See the StifleR Server and StifleR Dashboard documentation for the installation requirements and procedures.

  • Note that StifleR supports these OS versions: Windows Server 2019 or above; Windows 11; Windows 10 LTSC 2019 or later

  • StifleR requires .NET Framework 4.8, IIS, and has specific firewall and certificate requirements

• DeployR 1.0 itself (which should normally be installed on the same server as StifleR) requires:

  • A supported version of Microsoft SQL Server, Express edition or higher. This database is used to store DeployR metadata and progress tracking information.

  • The BranchCache optional component

  • The latest .NET 8.0 components, available for download from Microsoft:

    • .NET Runtime 8.0.17

    • .NET Desktop Runtime 8.0.17

    • ASP.NET Core Runtime 8.0.17

  • The latest PowerShell 7.4 release, available for download from Microsoft

  • The Microsoft Assessment & Deployment Toolkit (ADK) for Windows 11 (latest release is recommended)

  • Certificates for secure communication (TLS/SSL)

  • For Linux bare metal deployment support, the Windows Subsystem for Linux (WSL) is needed, so the server needs to either support hardware-assisted virtualization, or in the case of a virtual machine, nested virtualization

Note that the DeployR service will normally execute using the LocalSystem account. A separate service account can be used if desired.

Note: Ensure that the StifleR Dashboard can be accessed from the DeployR server, and you can successfully authenticate using Windows credentials. If this works from a remote computer but results in an authentication loop from the DeployR server, this could be an issue with a Windows LSA loopback setting. See https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/accessing-server-locally-with-fqdn-cname-alias-denied for more information. This is a common issue when using a CNAME alias for accessing the server, but can occur in other scenarios as well.
