Thanks for the additional details! A black screen after trying to install the TeleGuard app can sometimes occur due to various reasons. Let's troubleshoot this step-by-step.

1. Check Your System Requirements: Ensure your Windows 10 system meets the minimum requirements for the TeleGuard app. This typically includes adequate space on your hard drive and an updated version of Windows.

2. Reboot Your Computer: Sometimes, simply restarting your computer can resolve temporary glitches. Please do this first before proceeding to further steps.

3. Run as Administrator: Right-click on the TeleGuard installation file and select "Run as Administrator." This may provide the necessary permissions for the installation.

4. Compatibility Settings: If the installation file still leaves you with a black screen, you can try running the installer in compatibility mode:
- Right-click on the installer file.
- Click on "Properties."
- Navigate to the "Compatibility" tab.
- Check "Run this program in compatibility mode for:" and select an earlier version of Windows (like Windows 7) from the drop-down menu. Click "OK" and try installing again.

5. Disable Antivirus Temporarily: Sometimes antivirus software may interfere with installations. You could try disabling your antivirus temporarily during the installation process. Just remember to turn it back on afterward.

6. Check for Windows Updates: Make sure your Windows 10 system is up-to-date:
- Go to "Settings" > "Update & Security" > "Windows Update," then click "Check for updates" and install any pending updates.

7. Re-download the Installer: It’s possible the installation file got corrupted. Try downloading the latest version of the TeleGuard installer from the official website here.

After you try these steps, let me know how it goes. If the black screen persists, we may need to explore other options or escalate this to higher-level support. Are you satisfied with the solution I provided?
