What it needs to run.

PowerShell

5.1, or 7.x

Operating system

Windows for the sense stages that read local services. Windows PowerShell 5.1 or PowerShell 7. Both are supported and the licence gate works on either — the module ships a build for each runtime and loads whichever one your shell can run

Active Directory

Read access for audits. Write rights on the target account for Execute. The RSAT ActiveDirectory module: required. It is declared in the module manifest, so importing SpnManager without RSAT installed fails outright rather than quietly skipping the directory work

Optional modules

ADFS, Exchange Management Shell, SharePoint: used when present; guided fallback when absent.

.NET

The C# engine: .NET 8 on PowerShell 7, or .NET Framework 4.7.2 and later on Windows PowerShell 5.1. The module ships both builds and loads whichever one your shell can run

Network

LDAP to a domain controller. WinRM to hosts you audit remotely; unreached hosts are reported, not skipped.

Marketplace purchases receive an entitlement, not a different binary. How the entitlement is presented to the module: a signed token you set as the SPNMANAGER_LICENSE_TOKEN environment variable on the machine that runs SpnManager. The module reads it from there. No separate installer, no different binary, and nothing is written to the module folder. See License →.

Release artefacts are signed. Signing key, fingerprint, and verification steps live on the trust center →.
