MD-102 Manage applications Practice Question
A company uses Microsoft Intune to manage iOS and Android devices. Users report that some line-of-business (LOB) apps fail to install with error '0x87D1041C'. The apps are signed and deployed as device-required installs. What is the most likely cause?
⚠ Common exam trap
Test-takers frequently confuse error 0x87D1041C with a user assignment or OS version issue, but the specific error code directly points to a certificate mismatch, not a policy or compliance failure.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The app is signed with a different certificate than the one uploaded to Intune.
Error 0x87D1041C in Intune indicates a signature mismatch. When a line-of-business (LOB) app is deployed as a device-required install, the app binary must be signed with a certificate that has been uploaded to the Intune console. If the signing certificate used to sign the app differs from the one uploaded, Intune rejects the installation because it cannot verify the app's integrity and trust chain.
