FC0-U71 Practice Question: Refer to the exhibit
Exhibit
Error log from software installer: [Error] Failed to register DLL: C:\Program Files\MyApp\helper.dll HRESULT: 0x80070005 Description: Access is denied.
Refer to the exhibit. What is the most likely cause of this installation error?
⚠ Common exam trap
CompTIA often tests the distinction between permission errors and resource errors, so the trap here is that candidates confuse a privilege-related error with a disk space or file corruption issue, especially when the error message does not explicitly say 'administrator'.
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
✓
Lack of administrative privileges
The error message indicates that the installation cannot proceed because the user lacks the necessary permissions to write to protected system directories or registry keys. On Windows, installing software typically requires administrative privileges to modify the Program Files folder, system registry, and other protected resources. Without these privileges, the installer is blocked by User Account Control (UAC) or the operating system's security policies, resulting in this specific error.
