How to Fix Marvel Rivals Error Code 10 on PC
We have gone through several threads and gathered all working solutions suggested by the players. Go through this comprehensive guide, and learn how you can fix this frustrating error and get back in the game.
1. Run Network Diagnostics and Relaunch the Game
First, try running the built-in Network Diagnostics tool within the game or launcher settings. This diagnostic tool checks for potential connectivity issues between the game servers and your PC. Once the diagnostic completes, exit the game entirely and close the launcher. Then, restart your PC and relaunch the game. Several players claim that this step solved the issue for them as it helps to reset the game-specific network connections.
2. Graphics and Network Driver Update
Old drivers are usually the culprit behind compatibility with most modern online games. So, for the best gaming experience, try updating your graphics card driver from NVIDIA, AMD, or Intel and network drivers. Additionally, you can also use utilities like NVIDIA GeForce Experience, AMD Radeon Software, or Intel Driver & Support Assistant to get the GPU driver update.
For network drivers, refer to the official website of your motherboard or network card manufacturer.
3. Add Marvel Rivals as a Non-Steam Game
If you are going to play the game via Steam but have the game installed on Epic, then you can add Marvel Rivals as a Non-Steam Game. Here is how you can do it:
Open up Steam. Go to Library >> Add a Game >> Add a Non-Steam Game, and choose from the list Marvel Rivals. If it doesn’t appear, go into the installation folder, manually locate the.exe file of the game, and add that.
That way, you will still have the Steam interface and everything including the in-game overlay, but you will be able to play through the Epic version of Marvel Rivals.
4. Copy Game Files to Steam Properly
This workaround may help those players who run the game on Steam with a copy available on Epic Games. First of all, start downloading the game on Steam but pause the process as soon as it starts. Then locate the files of the game in your Epic installation, usually at C:\Program Files\Epic Games. Copy it and paste it under Steam/steamapps/common to a directory called “MarvelRivals.” After that, restart Steam download just to check if the files are okay.
5. Reinstall the Game in Steam
If the error persists with the Epic Games version, try uninstalling the game from Epic Games and then downloading it via Steam instead. Many players claim that the error code was occurring to the Epic Games version, and switching to Steam resolved the problem. To do this, purchase or redeem the game on Steam, download and install it, and then launch it from Steam. This might bypass any launcher-related issues specific to Epic Games.
That’s all about how to solve Marvel Rivals error code 10 on PC.
