## TL;DR
An Intune Win32 app stuck on downloading usually means the content never reached the device: delivery optimization blocked, the Intune management extension unhealthy, or the package too large for the network. Check the client-side logs to see where the download stalls.

## The query
```text
intune win32 app install stuck on "downloading"
```

## Use this when
- Intune app status stuck on downloading for hours
- one app stalls while others install fine
- large packages failing on slow networks

## Not for
- apps that download but fail to install (check install logs)
- Microsoft Store apps (different pipeline)
- devices not enrolled in Intune

## Steps
1. On the device, confirm it is online and the Intune management extension is healthy. Expected output: the agent reports in normally
2. Check the Intune Management Extension log on the device for the download attempt. Expected output: the log shows where the download stalls
3. Verify delivery optimization or the CDN endpoints are reachable from the device network. Expected output: content endpoints reachable
4. Check the package size and the device's free disk space. Expected output: enough space for the download
5. Retry the install from Company Portal and watch the log in real time. Expected output: the download progresses or a new error appears
6. If it repeatedly stalls, repackage with smaller content or split the payload. Expected output: a package that downloads cleanly
