Hi! I understand that when you try to open Mech Arena on your Windows device, it just shows that it's "running" without actually launching. To help you better, could you tell me if you see any black screen, error messages, or does it just stay stuck on "running"? Also, have you tried any fixes so far?

In the meantime, here are some straightforward steps to try:

1. Restart your PC: Sometimes a fresh reboot clears any stuck processes.

2. Check Task Manager: Press Ctrl + Shift + Esc, look under the Processes tab for Mech Arena or related Plarium processes. If you see one, right-click and End Task to fully close it before restarting the game.

3. Run as Administrator: Right-click the Mech Arena shortcut or .exe, and select "Run as Administrator" to give it full permissions.

4. Clear Cache / Temporary Files: Navigate to the game’s install folder or cache location and delete temporary files that might be causing issues.

5. Update the Game and Windows: Ensure both Mech Arena and your Windows 10 are fully updated.

6. Reinstall the game: If the above don’t help, uninstall Mech Arena and reinstall it fresh from the official source.

If any of these steps are new to you or if you've tried some already, let me know which ones. I can guide you through more advanced options or check if there are any known issues with Mech Arena for Windows that might be impacting you specifically.

Are you ready to try these steps together?
