How to Fix Marvel Rivals running install script issue

The "running install script" issue in Marvel Rivals, primarily affecting the Steam Client version, can be a frustrating roadblock for players eager to jump into the game. While this error is not universally common, understanding its potential causes and solutions can save you a lot of troubleshooting time.

Possible Causes of Marvel Rivals "Running Install Script" Issue

The exact root cause of the "running install script" error has not been officially confirmed by the developers. However, community observations and troubleshooting efforts point to several likely culprits:

• Corrupted or Missing Game Files: During download or updates, game files can become corrupted or go missing, leading the Steam client to get stuck trying to execute an incomplete or faulty installation script.
• Steam Download Cache Issues: The Steam client's download cache can sometimes contain incomplete or erroneous data, interfering with the proper execution of game installation scripts.
• Dependency Problems: Games often rely on external software components like Microsoft .NET Framework or Visual C++ Redistributables. If these dependencies are not correctly installed, corrupted, or are of an incompatible version, the game's initial setup script (which might include installing these) can fail. This is a very common reason for "running install script" errors on Steam for various games.
• Outdated Graphics Drivers: While less directly tied to the install script phase, outdated graphics drivers can cause compatibility issues that manifest in various ways, including preventing a game from launching correctly after installation.
• Antivirus/Firewall Interference: Security software can sometimes falsely identify game files or the installation process as a threat, blocking necessary operations and causing the script to hang.
• Steam Client Glitches: Rarely, the Steam client itself might encounter a temporary bug or a registry issue that prevents it from properly completing the installation process.

Possible Fixes for Marvel Rivals "Running Install Script" Issue

Here are some potential solutions you can try to resolve the "running install script" issue for Marvel Rivals:

Verify Game Files (Highly Recommended First Step): This is often the most effective solution as it repairs any corrupted or missing game files without requiring a full reinstallation.

• Open the Steam client.
• Go to your Library section.
• Right-click on Marvel Rivals and select Properties.
• Navigate to the Installed Files tab (or "Local Files" on older Steam versions).
• Click on "Verify integrity of game files..." and wait for the process to complete.

Clear Download Cache: Clearing Steam's download cache can resolve issues stemming from incomplete or corrupted download data.

• Open Steam and go to Settings (Steam menu -> Settings).
• In the Downloads section, click on "Clear Download Cache."
• Restart Steam and try to launch Marvel Rivals again.

Reinstall Microsoft Visual C++ Redistributables: This is a very common fix for "running install script" errors across many Steam games. Corrupted or missing C++ redistributables are a frequent cause.

• Uninstall Existing Versions:
• Go to Control Panel -> Programs -> Programs and Features (or Settings -> Apps -> Apps & features on Windows 10/11).
• Uninstall all entries named "Microsoft Visual C++ Redistributable". You might have several versions (e.g., 2008, 2010, 2012, 2013, 2015-2022) for both x86 and x64 architectures. Uninstall all of them.
• Download and Reinstall the Latest Versions:
• Go to the official Microsoft website for the latest supported Visual C++ Redistributable downloads: https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist
• Download and install both the x86 and x64 versions of the "Visual Studio 2015, 2017, 2019, and 2022" redistributable (this single package covers multiple years).
• It's also advisable to download and install the Visual C++ Redistributable for Visual Studio 2013 (if not already present), as some games still rely on it.
• Restart your PC after installing.

Update Graphics Drivers:Outdated drivers can cause various game launch issues.

• Identify your graphics card (NVIDIA, AMD, or Intel).
• Go to the official website of your graphics card manufacturer (NVIDIAGeForce Drivers, AMD Drivers & Support, Intel Driver & SupportAssistant).
• Download and install the latest drivers for your specific GPU model.
• Restart your PC after the driver update.

Temporarily Disable Firewall/Antivirus:

• Temporarily disable your Windows Defender Firewall and any third-party antivirus software.
• Try launching Marvel Rivals. If it works, you'll need to add an exceptionfor the Epic Games Launcher and Marvel Rivals executable in yoursecurity software.
• Remember to re-enable your security software afterward.

Toggle Auto-Updates:This can sometimes refresh how Steam handles updates.

• Launch the Epic Games Launcher (if applicable, though the problem is stated for Steam) and navigate to the Library section.
• Find Marvel Rivals.
• Click on the three-dot menu icon and choose the Manage option.
• Toggle off the switch corresponding to the Auto Update feature.
• Restart the Steam Client.
• After the restart, try launching the game. You can then try toggling Auto Update back on if the issue is resolved.

Reinstall Marvel Rivals:If all other fixes fail, a clean reinstallation might be necessary. Your in-game progress and settings are typically saved on the Steam cloud,so you won't lose them.

• Uninstall: In the Steam client, go to Library, right-click Marvel Rivals, hover over "Manage," and select "Uninstall."
• Reinstall: After uninstallation, you can reinstall the game from your Steam Library.

By systematically applying these fixes, you should be able to resolve the"running install script" issue and enjoy Marvel Rivals withoutinterruption.
