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
Similar to B, this is a symptom fix; the underlying issue may be permissions.
- ✓
Run the installer as Administrator.
Why this is correct
This addresses the warning and may resolve the missing component errors due to permission issues.
- ✗
Install .NET Framework 3.5.
Why it's wrong here
This is a specific fix but may not resolve the root cause if admin rights are missing.
