What is usually the easiest way to fix an application that won’t start anymore?
- A.
Run your virus scanner to fix the application because you probably have a virus.
- B.
Reboot your computer to fix the application because it’s probably a system error.
- C.
Uninstall and reinstall the application to reset the application completely.
- D.
Run Windows Registry repair software to fix the application because it’s probably a registry error.
Correct Answer
B. Reboot your computer to fix the application because it’s probably a system error.Explanation
Often, a simple reboot of the computer can resolve issues with applications that won't start. This is because a reboot can help clear temporary system glitches or conflicts that may be preventing the application from launching.
Option C (Uninstall and reinstall the application) is also a valid troubleshooting step. If the application's files or settings have become corrupted, reinstalling it can provide a fresh start.
Options A and D are generally not recommended as first-line solutions. Running a virus scanner (Option A) is essential for security but may not directly fix an application launch issue. Similarly, using registry repair software (Option D) can be risky and is typically unnecessary for resolving most application startup problems.Rate this question:
