MD-102 Manage applications Practice Question
You are an Endpoint Administrator for a company using Microsoft Intune. A Windows app (Win32) app has been deployed as Required to a pilot group of 20 devices. Reports show the app installed successfully on 18 devices but failed on 2 devices with the error 'The application was not detected after installation completed successfully.' You confirm the installer runs silently and exits with code 0 on the failing devices. What is the most likely cause?
⚠ Common exam trap
The trap here is focusing on the installer or exit code, when the error text explicitly indicates the install succeeded and only the post-install detection step failed.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The detection rule configured for the app does not match the state the installer actually produces on those devices.
The message 'not detected after installation completed successfully' is generated when the installer returns a success code but the detection rule evaluation finds nothing matching. Because the same package works on other devices, the detection rule is the component that needs correction for the affected devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The app's requirement rules exclude those two devices because they run an unsupported Windows build.
Why it's wrong here
If requirement rules excluded the devices, the app would not be offered or installed on them, and the status would show as not applicable rather than a post-install detection failure. Requirement rules gate applicability before installation, so they cannot produce this specific error after a successful install.
- ✗
The devices are not enrolled in the Intune Management Extension and therefore cannot run Win32 apps.
Why it's wrong here
If the Intune Management Extension were missing or unhealthy, the app would not have attempted installation at all and the status would reflect that, not a post-install detection failure. Since the installer ran and exited with code 0, the extension was functioning on the failing devices.
- ✗
The install command line for the app is incorrect and causes the installer to silently skip installation.
Why it's wrong here
An incorrect install command line would typically produce a non-zero exit code or an immediate failure rather than a successful exit followed by a detection failure. The reported error specifically occurs after a successful install, so the command line is not the likely cause here.
- ✓
The detection rule configured for the app does not match the state the installer actually produces on those devices.
Why this is correct
The error message means Intune ran the installer, saw a success exit code, but then evaluated the detection rule and found no match, so it treats the install as failed. A detection rule that checks the wrong path, registry hive, or version on those devices explains why the same package succeeds elsewhere.
