FC0-U71 Practice Question: A technician is installing a legacy application…
Exhibit
[2023-10-05 14:32:10] Error: Failed to install MSXML6. Required component missing. [2023-10-05 14:32:10] Error: The installation of .NET Framework 3.5 failed. [2023-10-05 14:32:10] Warning: The application requires Administrator privileges.
A technician is installing a legacy application on Windows 10 and receives an error log indicating 'Access Denied'. Which of the following should the technician do FIRST?
⚠ Common exam trap
The trap here is that candidates see a legacy application and immediately assume a missing dependency (like MSXML or .NET) is the cause, overlooking the simple permission issue that is the most common first step in troubleshooting installation failures.
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
✓
Run the installer as Administrator.
Legacy applications often require elevated privileges to install on Windows 10 because they may attempt to write to system directories or registry keys that are protected by User Account Control (UAC). Running the installer as Administrator is the simplest and most common first troubleshooting step to resolve permission-related issues before considering other solutions like missing dependencies or application upgrades.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Install MSXML6.
Why it's wrong here
MSXML6 provides XML parsing libraries, not permission resolution, so it cannot clear an 'Access Denied' error raised when the installer writes to protected locations. It is tempting because legacy applications often require specific MSXML versions, making it the right fix when the error log names a missing XML component rather than a permissions failure.
- ✓
Run the installer as Administrator.
Why this is correct
'Access Denied' during installation indicates the process lacks rights to write to protected locations such as Program Files or the registry. Running the installer as Administrator elevates the token, granting the permissions needed to complete installation.
- ✗
Install .NET Framework 3.5.
Why it's wrong here
.NET Framework 3.5 supplies runtime libraries for legacy code, not filesystem or registry permissions, so installing it leaves the 'Access Denied' condition unresolved. It is tempting because legacy installers frequently fail without that runtime, making it correct when the log cites a missing .NET dependency instead of denied access.
- ✗
Upgrade the application to a newer version.
Why it's wrong here
Upgrading the application replaces the software rather than resolving the permission problem, and it may not even exist for a legacy product. It would be correct where the vendor has released a build that officially supports Windows 10 and the current version is genuinely unsupported.
