🔹 3. Run System File Checker (SFC) Tool

- Open Start and search for
cmd. - Right-click on Command Prompt and select Run as Administrator.
- Type the following command and press Enter:
sfc /scannow
- Wait for the process to complete. It will scan and automatically fix any corrupted system files.
- Once done, restart your computer.
🔹 4. Check for Faulty RAM
If you recently added new RAM to your PC, it might be the culprit:
- Shut down your PC.
- Remove the newly installed RAM.
- Restart your computer and try running the application again.
If the issue disappears, the new RAM stick might be faulty or incompatible.
🔹 5. Temporarily Disable Antivirus Software
Sometimes, antivirus software may block apps from launching:
- Search for Windows Security and open it.
- Go to Virus & Threat Protection.
- Click Manage Settings.
- Toggle Real-time protection to Off.
If you’re using a third-party antivirus, you may need to disable it from its interface.
Try opening the application again. If it launches successfully, the antivirus was likely causing the issue. Consider adding the application to the antivirus exception list.
