MD-102 Manage applications Practice Question
You are troubleshooting an app deployment issue. A Win32 app fails to install on some Windows 10 devices. The Intune management extension logs show error code 0x80070643. What is the most likely cause?
⚠ Common exam trap
Test-takers frequently confuse 0x80070643 with a generic installation failure and assume it indicates a corrupted package or permission issue, but the specific error code is tied to reboot-pending conditions in Windows Installer and Intune deployments.
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
✓
A pending reboot from a previous installation is blocking the install
Error code 0x80070643 translates to 'ERROR_INSTALL_FAILURE' and is commonly associated with a pending reboot that blocks the installation of a Win32 app via Intune. The Intune Management Extension checks for pending reboot status before executing app installations; if a reboot is required, the installation fails with this error to prevent system instability.
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 package is corrupted
Why it's wrong here
Corruption would cause a different error.
- ✗
The device does not meet the minimum OS version requirement
Why it's wrong here
That would be a different error code.
- ✓
A pending reboot from a previous installation is blocking the install
Why this is correct
0x80070643 often means 'Installation failure, reboot required'.
- ✗
The user does not have admin privileges
Why it's wrong here
If installation behavior is 'system', it runs as SYSTEM, so privileges are not the issue.
