How to Fix Intune Management Extension Not Installing on Windows Devices
You might see that PowerShell scripts do not work. App installs can freeze on your Windows devices. This can happen if the Intune Management Extension does not install. Devices set up with sysprep images may miss this extension. Manual enrollment or using unsupported Windows versions can also cause this. Without the extension, Win32 apps will not install. The Company Portal cannot show status updates. Sometimes, the extension removes itself or never shows up. Devices then become unmanaged and scripts do nothing.
Key Takeaways
Look at your Windows version and check if your device is enrolled before you install the Intune Management Extension. This helps you avoid common problems.
Make sure your device has a good internet connection. Check that the firewall lets Microsoft services through for easy installation.
Check if the Intune Management Extension service is working. Look at the logs to find errors fast.
Try installing it by hand and use PowerShell sync commands if it does not install by itself.
Follow each troubleshooting step closely. Watch your device after each fix to make sure it works well and runs apps without trouble.
Check Prerequisites
Before you try to fix problems, make sure your device has everything it needs for the installation to work. If you skip a step, the Intune Management Extension might not work right.
Windows Version
You need to use a Windows version that is supported. Old or unsupported Windows versions often cannot install the extension.
You need Windows 10 version 1607 or newer.
Only Enterprise, Pro, or Education editions will work.
Devices with versions that are too old will not get updates or help.
Here is a table that lists some common Windows version problems and what you should do:
Tip: Always check your Windows version before you enroll in Intune. This can stop many problems before they start.
Device Enrollment Type
How you enroll your device is important.
Devices must be enrolled in Intune. Just registering is not enough.
Auto-enrollment starts the extension install. Manual enrollment might not.
If you use a sysprep image, make sure it is set up the right way.
If sysprep fails or there are duplicate SIDs, Intune may think many devices are the same. Only the first device gets the extension. The others do not get the C:\ProgramData\Microsoft\IntuneManagementExtension folder and show errors in the event viewer.
Note: If you see weird device names or missing folders, check if your imaging process made duplicate SIDs.
Azure AD Join Status
Your device must be joined or hybrid-joined to Azure AD (now called Entra ID).
Devices joined with Entra ID join or Hybrid Entra ID join and enrolled in Intune will start the extension install.
The Enrollment Status Page shows app installs and policies during setup.
If the join status is wrong, Intune cannot manage the device or install the extension.
Remember: The right join status makes sure your device is registered and can talk to Intune services.
Checking these things helps you avoid most install problems. If you follow these steps, your device will be ready for a smooth Intune Management Extension install.
Network and Endpoint Access
Internet Connection
Your device must have a good internet connection to work. It needs this to install management tools and get updates. If your device cannot reach Microsoft servers, it will miss needed files. Check if your device can go online and visit websites. Sometimes, weak Wi-Fi or a loose cable stops the install. Try opening a browser and visit some websites. If you see errors or slow pages, fix your internet first.
Tip: Use a wired network if you can. Wired networks are usually faster and more stable than Wi-Fi.
Firewall and Proxy
Firewalls and proxies keep your network safe, but they can block needed traffic. If your firewall or proxy blocks Microsoft service URLs, your device cannot get apps or scripts. Make sure your firewall lets traffic go to Microsoft Store and Windows Package Manager endpoints. For example, if your firewall blocks https://storeedgefd.dsx.mp.microsoft.com/v9.0/manifestSearch, your device cannot install apps from Intune. Proxy settings must let key Microsoft domains work without login. Do not turn on SSL inspection for these domains because it can break secure connections.
Some common firewall and proxy problems are:
Blocking outgoing traffic to Microsoft Intune service endpoints.
Not allowing needed URLs for Intune and Windows Autopilot.
Stopping managed devices from using the internet.
Not letting all needed endpoints send traffic out.
Missing some Microsoft URLs in your allowed list.
Check your firewall and proxy rules. Update them so all needed traffic is allowed.
Intune Service Endpoints
Your device must reach some Microsoft endpoints to install and use management tools. The table below lists the main network needs:
If you allow these endpoints and open the right ports, your device can talk to Microsoft services. This helps you install apps, run scripts, and manage devices without trouble.
Intune Management Extension Installation
Service Status
Check if the Intune Management Extension service is running. First, look in the Windows registry. Go to HKLM\SOFTWARE\Microsoft\IntuneManagementExtension\Win32Apps\<user>\<appid>. This shows if the install worked or if there are errors. Next, open Task Scheduler. Find the "Intune Management Extension Health Evaluation" task. This task checks the service health every day. It tries to fix problems. You can restart the service in Task Manager. You can also use PowerShell to start a sync. Use registry URL monikers like intunemanagementextension://syncapp to refresh the service.
Restarting the service or syncing can fix small problems fast.
Directory and Logs
Important logs are in C:\ProgramData\Microsoft\IntuneManagementExtension\Logs. These logs show what happens during install. Some main log files are:
IntuneManagementExtension.log(shows general activities and policy issues)AppWorkload.log(helps with Win32 app deployment)AgentExecutor.log(tracks PowerShell scripts and remediation tasks)ClientHealth.log(shows agent health checks)AppActionProcessor.log(shows app install and detection checks)
Use the tool CMTrace.exe to read these logs. On x64 computers, set antimalware exclusions for C:\Program Files (x86)\Microsoft Intune Management Extension\Content and C:\windows\IMECache. This helps stop install problems.
Error Codes
When you see errors, look at the error codes. These codes tell you what went wrong. Here is a table of common error codes and what they mean:
If you see one of these codes, check the logs. Try rebooting or review your app requirements.
Troubleshooting and Solutions
If the Intune Management Extension will not install, you can try different steps. These steps help you find out what is wrong. They also help you fix the problem so your device can run scripts and install apps.
Manual Installation
Sometimes, the extension does not install by itself. You can try to put it on the device yourself. Here is what you can do:
Check if the download link is broken. Sometimes, the link has 'rc' in it and that causes trouble.
Take out the 'rc' part from the link to fix it.
Download the IntuneWindowsAgent.msi file from the new link.
Run the MSI file on the device that has the problem.
If this works, tell Microsoft support. They can help make sure the link is good for everyone in your group.
If you install the extension by hand, scripts and apps may start working right away.
Log Review
You need to look at the logs to see why the extension did not install. The logs show what happened step by step during the install. They can tell you if files are missing or if there are permission problems or other errors.
The logs are in C:\ProgramData\Microsoft\IntuneManagementExtension\Logs. Use CMTrace to open the log files. Look for files like IntuneManagementExtension.log and AgentExecutor.log. These files show errors and warnings about scripts and app installs.
You should also check the registry. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Autopilot\EnrollmentStatusTracking. Look for keys like DevicePreparation, Setup, and ESPTrackingInfo. These keys show if the extension installed, if the device synced, and if policies were set. If you see error code 1603, it means a big problem happened. Other codes like 1618 or 1722 mean different problems. The logs and registry together help you find the real cause.
Tip: Always check if the MDM certificate is good. Also, make sure the folder at
C:\Program Files (x86)\Microsoft Intune Management Extension\Content\incominghas the right files.
Advanced Fixes
If the easy steps do not work, you can try harder fixes. These steps help you fix tough problems with the extension.
Use the Intune admin center to get more info from the device. This gives you more details about the install.
Open the Troubleshooting blade in the Intune admin center. Here, you can see app status, policies, and if the device is following the rules.
Try Microsoft self-help tools in the Microsoft 365 admin center. These tools can find and fix common problems by themselves.
Look at all the main logs again with CMTrace. Focus on errors and warnings in files like
IntuneManagementExtension.log,AgentExecutor.log, andAppActionProcessor.log.Check the Company Portal to see if the app is there and if the device tried to install it.
Make sure your install commands and detection methods are right. Wrong settings can stop the extension.
Follow best practices. Use the same types for deployment, simple detection, and keep your apps up to date.
For error codes like 0x80070002, check if the file paths in your install commands are right.
Use PowerShell to force a sync. Connect to Microsoft Graph, check the device sync, and run a sync command. You can also use the Intune Admin Center to sync many devices at once.
If you still have trouble, restart the device and try again. Sometimes, a restart helps the extension finish installing.
Note: Always watch the device after each fix. This helps you know if the problem is gone or if you need to try something else.
You can fix most install problems by following simple steps. First, check if there are any service outages. Make sure your device meets all the needed requirements. Look at event logs and MSI logs to find error codes or blocked files. Use the Intune admin center to watch app installs and see device status. If you still have problems, collect diagnostic info and ask Microsoft support for help. Checking logs often and watching your devices helps keep them safe and managed.
