Intune Deployment Guide

Intune requirements explained

Overview

Requirements control whether a device is eligible to install a Win32 app. Intune evaluates requirements before running the install command.

Correct requirements prevent apps from being offered to unsupported devices and reduce failed installations.

Built-in requirements

Common built-in requirements include operating system architecture, minimum operating system, disk space, memory, CPU count, and CPU speed.

Custom requirement rules

Custom requirement rules can use file, registry, or script-based checks when built-in rules are not enough.

How the flow works

02Requirements runEligibility checked

Practical reference

Area	What to check
Architecture	Limit install to 32-bit, 64-bit, or ARM64 where appropriate
Minimum OS	Prevent install on unsupported Windows versions
Disk/RAM/CPU	Avoid installs on devices that cannot support the app
Custom rule	Handle app-specific eligibility checks

Quick checklist

Use the minimum requirements that are actually needed.
Do not over-restrict pilot devices by accident.
Check requirements first when an assigned app never starts installing.

Troubleshooting checks

Issue	What to check
App never installs	Device may not meet requirements.
Only some devices install	Compare architecture and OS version.
Custom requirement fails	Review script output or registry/file path.
