1Kosmos Platform Prerequisites

Complete these steps in AdminX before deploying the agent. Installing the agent before completing these steps will cause authentication failures.

• Tenant / Community is set up — Tenant must be provisioned. Contact your 1Kosmos representative if you haven't done this.
• Active Directory — Configured via the AdminX Broker. Users must exist in the directory before they can authenticate. See Authentication Broker.
• Windows MFA application is configured in AdminX — Navigate to Applications > Windows MFA and confirm the application exists.
• At least one Adaptive Auth Journey is configured — Users without a matching journey will see the default authentication options. See AdminX Configuration.
• Users are enrolled in their authentication method — the mobile app must be linked for Push / TOTP / QR Code authentication; 1Key must be enrolled for FIDO; Behavior Auth + PIN enrolls at first login.

Installer Selection Guide

Two installer formats are available. Choose the appropriate format before you begin; switching formats later requires a full uninstall and reinstall.

EXE vs MSI

Feature	EXE	MSI
Silent install	✅ (/SILENT, /VERYSILENT)	✅ (/qn)
SCCM / Intune / GPO	⚠️ Possible but more complex	✅ Native support
Auto-installs dependencies	✅ Yes	❌ Must be pre-installed
Configuration method	command-line params + REGCONFIG.ini (v2.x)	Windows Registry via registryconfig.ini
Supported CP version	v2.x	v2.x only

Migrating from v2.1 to v2.2? See Upgrade & Migration. Note that config.json is not used in v2.x MSI installations, all configuration moves to the Windows Registry.
