Gameloop Error Code 16: Fixes for Windows

Gameloop error code 16 on Windows stops the emulator from launching or crashes it mid-game, usually due to a corrupted installation, outdated graphics drivers, or a conflict with Windows security features. This guide walks you through the most effective fixes, from clearing the cache to adjusting your BIOS settings, so you can get back to playing Android games on your PC.

What Is Gameloop Error Code 16?

Gameloop is the official Android emulator for PC, developed by Tencent, primarily used to play mobile games like PUBG Mobile and Call of Duty: Mobile. Error code 16 typically appears as a pop-up window with a message like “An error occurred while starting the game” or simply “Error Code: 16.” It can happen at launch, during a game update, or while in the middle of a match. The root cause is almost always a local issue on your Windows machine, not a problem with the game servers or your internet connection.

Common triggers include:

• Corrupted cache files from a previous session or failed update.
• Outdated or incompatible graphics drivers (especially after a Windows update).
• Windows Defender or third-party antivirus blocking Gameloop’s core processes.
• Virtualization (VT-x/AMD-V) disabled in the BIOS, which Gameloop needs to run smoothly.
• Insufficient permissions to write to the installation folder or the emulator’s data directory.

Before You Start: Quick Checks

Before diving into more complex fixes, spend two minutes on these basics. They resolve a surprising number of cases.

1. Restart your PC. A fresh boot clears temporary memory locks and stops background processes that might interfere.
2. Run Gameloop as administrator. Right-click the Gameloop shortcut and select “Run as administrator.” This gives it the file access it often needs.
3. Check your internet connection. A dropped connection during a game update can corrupt files. Try a wired connection or restart your router.
4. Close other resource-heavy apps. Gameloop is demanding; close browsers, streaming apps, and other games to free up RAM and GPU resources.

Fix 1: Clear Gameloop’s Cache and Data

Corrupted cache is the most frequent cause of error code 16. Gameloop stores temporary data in its installation folder, and a crash or forced shutdown can leave that data in a broken state.

1. Close Gameloop completely (check the system tray for the icon and right-click to exit).
2. Open File Explorer and navigate to the Gameloop installation folder. By default, this is C:\Program Files\Gameloop\ or C:\Program Files (x86)\Gameloop\.
3. Delete the Cache folder inside that directory. If you don’t see it, skip to step 4.
4. Press Win + R, type %temp%, and press Enter. Delete everything inside the Temp folder (you can skip files that are in use).
5. Relaunch Gameloop. It will rebuild the cache from scratch.

If the error persists, also try the in-app repair tool: open Gameloop, click the gear icon (Settings), then select “Repair” or “Check for Updates.” This re-downloads any missing or damaged files.

Fix 2: Update Your Graphics Drivers

Gameloop relies heavily on your GPU to render Android games. A driver that is outdated, or that was recently updated and introduced a bug, can trigger error code 16. This is especially common after a major Windows 10 or Windows 11 feature update.

1. Press Win + X and select “Device Manager.”
2. Expand “Display adapters,” right-click your graphics card (NVIDIA, AMD, or Intel), and choose “Update driver.”
3. Select “Search automatically for drivers.” Windows will look for the latest version.
4. If Windows doesn’t find anything, go to the manufacturer’s website (NVIDIA, AMD, or Intel) and download the latest driver for your specific model. Use their auto-detect tools if available.
5. After installing, restart your PC and try Gameloop again.

A clean driver install (using the “Custom” option and checking “Perform a clean installation”) is worth trying if the problem started right after a driver update.

Fix 3: Disable Antivirus or Add Exclusions

Windows Defender and third-party antivirus programs sometimes flag Gameloop’s files as suspicious because the emulator injects code into processes to run Android apps. This can cause the emulator to be blocked or its files to be quarantined, leading to error code 16.

First, check if your antivirus has a “quarantine” or “threat history” section. If you see any Gameloop-related files, restore them and add an exclusion for the entire Gameloop folder. In Windows Defender, go to Settings → Privacy & Security → Windows Security → Virus & threat protection → Manage settings → Exclusions. Add the Gameloop installation folder and the %temp% folder as exclusions.

If you use a third-party antivirus, add the same exclusions in its settings. As a temporary test, you can also disable real-time protection entirely, but remember to re-enable it after testing. If the error disappears with the antivirus off, you’ve found the culprit.

Fix 4: Enable Virtualization in BIOS

Gameloop uses hardware virtualization to run Android in a smooth, efficient way. If virtualization is disabled in your BIOS/UEFI, the emulator may fail to start or crash with error code 16. This is a common issue on older PCs or after a BIOS reset.

1. Restart your PC and press the key to enter BIOS/UEFI (usually Del, F2, or F10 – check your motherboard manual).
2. Look for a setting called “Intel Virtualization Technology” (VT-x), “AMD-V” (SVM), or simply “Virtualization.” It’s usually under the “Advanced” or “CPU Configuration” tab.
3. Set it to Enabled.
4. Save and exit (usually F10), then boot into Windows.

You can verify that virtualization is active in Windows by opening Task Manager (Ctrl + Shift + Esc), going to the “Performance” tab, and checking “Virtualization” at the bottom. If it says “Enabled,” you’re good.

Fix 5: Reinstall Gameloop Completely

If none of the above work, the installation itself is likely corrupted beyond repair. A complete reinstall removes all traces and gives you a clean slate.

1. Uninstall Gameloop via Settings → Apps → Apps & features (or Control Panel → Programs and Features).
2. After uninstalling, delete the remaining Gameloop folders. Check C:\Program Files\Gameloop, C:\ProgramData\Gameloop, and %appdata%\Gameloop.
3. Restart your PC.
4. Download the latest version from the official Gameloop website (do not use third-party download sites).
5. Install it and run it as administrator.

This also ensures you’re on the latest version, which may have fixed the bug that caused error code 16 in the first place.

Frequently Asked Questions

Is error code 16 caused by my Windows version?

Not directly. Error code 16 is not specific to any Windows version, but it can appear after a Windows update changes security settings or driver compatibility. The fixes above work on Windows 10 and Windows 11 alike.

Will reinstalling Gameloop delete my games and progress?

Your game progress is tied to your game account (e.g., your PUBG Mobile account), not to the emulator. Reinstalling Gameloop will remove the installed games, but you can re-download them and log back in. Your progress will be safe.

Can I fix error code 16 by lowering my graphics settings?

No. Error code 16 is a system-level error, not a performance issue. Changing in-game graphics settings won’t help. However, if you’re experiencing crashes during gameplay, lowering settings might reduce the chance of a crash, but it won’t stop error code 16 specifically.

What if I have an AMD processor – do these fixes still apply?

Yes, all the fixes apply. For AMD, just make sure you enable “SVM” (Secure Virtual Machine) in the BIOS instead of Intel VT-x. The rest of the steps are identical.

Why does Gameloop need virtualization enabled?

Gameloop is an Android emulator, which means it runs a full Android operating system inside Windows. Virtualization lets the CPU efficiently run that second OS, so without it, the emulator either fails to launch or runs so poorly that it crashes. Enabling it is a standard requirement for most Android emulators on PC.
