Welcome to the RetRO Troubleshooting Hub. If you’re having problems launching or running the client, this page covers the most common fixes. Follow the steps below depending on the issue you’re facing.

hashtag
1. Getting Started

Always run as Administrator

Right–click and set the following files to Run as Administrator:

  • RetRO.exe

  • RetRO Patcher.exe

  • opensetup.exe

Recommended setup

  • Set Compatibility Mode of RetRO.exe to Windows 7 (Win10/11 users) or XP Service Pack 3.

  • Install the game in a custom folder (e.g. C:\Games\RetRO\) instead of Program Files.

  • Update your client through Valkaria Patcher.exe regularly.

2. Antivirus / Firewall Warnings

Some security software may mistakenly flag RetRO files because of our anti-cheat systems.

✅ Fix: Add the following as exceptions in your antivirus/firewall: - ValRO installation folder - RetRO.exe - RetRO Patcher.exe

Special note for Brazil

If you use Warsaw Bank Security Software, uninstall it before running ValRO. This software conflicts with Gepard Shield and prevents the client from running.

  3. Max Frame Rate → 60 FPS
