故障排除

MuhRO 故障排除

大多数问题无需重装 Windows 或禁用安全软件即可解决。请按顺序执行以下步骤，并在问题解决后停止。

开始之前

1. 关闭 Muh.exe、Muh_Patcher.exe 和 updater.exe。如果仍有进程未关闭，请使用任务管理器结束它。
2. 如果最近更新了 Windows、显卡驱动或运行库，请重启电脑。
3. 从 MuhRO 游戏文件夹启动 Muh_Patcher.exe。不要直接启动 Muh.exe。
4. 等补丁程序完成更新后再按 Play。
5. 打开 Game Setup，选择你的画面设置，并至少按一次 Save。
6. 如果出现错误，请在关闭错误窗口前保留完整文本或截图。

推荐的安装文件夹

请将 MuhRO 安装或解压到一个路径较短的本地文件夹，例如：

C:\Games\MuhRO

请避免将游戏安装在以下位置：

• C:\Program Files 或 C:\Program Files (x86)；
• Windows 或 System32 目录；
• 下载、桌面或文档文件夹；
• OneDrive 或其他云同步文件夹；
• 网络驱动器；
• 包含非英文字母、特殊符号或路径特别长的文件夹。

建议使用仅包含普通拉丁字母和数字的路径。不要在 ZIP 压缩包内运行补丁程序；请先解压完整客户端。

客户端问题

客户端无法启动、无报错闪退、提示 MSVCP/VCRUNTIME DLL 错误或随机崩溃

请尝试以下步骤：

1. 启动补丁程序，并确保所有更新都已完成。
2. 运行 Game Setup，选择一个普通分辨率并保存设置。
3. 安装以下两个最新版 Microsoft Visual C++ Redistributable：
   • Visual C++ x86
   • Visual C++ x64
4. 安装或修复运行库后重启 Windows。
5. 暂时关闭会向游戏注入覆盖层的软件，例如录制覆盖层、ReShade、RTSS 或类似工具。
6. 直接从 Intel、AMD 或 NVIDIA 更新显卡驱动。
7. 检查 Windows 安全中心或杀毒软件的“保护历史记录”，查看是否有文件从 MuhRO 文件夹中被移除。

32 位游戏客户端需要 x86 版 Visual C++ 运行库，64 位 Windows 上也是如此。不要从 DLL 下载网站下载单独的 DLL 文件。

启动客户端时出现空白错误

这通常发生在直接启动 Muh.exe 时。请始终启动 Muh_Patcher.exe，登录并通过补丁程序启动所选的游戏账号。

桌面快捷方式必须指向 Muh_Patcher.exe，而不是 Muh.exe。

“Cannot init D3D”或图形初始化错误

在补丁程序中打开 Game Setup，并尝试以下操作：

1. 选择 DirectX 9 并保存设置。
2. 如果 DirectX 9 无法使用，请测试 DirectX 7。
3. 尝试使用窗口模式，并选择常见分辨率，例如 1280×720 或 1920×1080。
4. 选择正确的显卡，尤其是在同时拥有核显和独显的笔记本电脑上。
5. 避免使用大于显示器的分辨率，或使用不受支持的刷新率组合。
6. 更新显卡驱动并重启 Windows。

如果提示缺少 D3DX9、XInput 或类似的旧版 DirectX 文件，请安装官方的 Microsoft DirectX End-User Runtime。

远程桌面会话和虚拟机可能无法提供所需的图形加速。请直接在电脑上测试游戏。

“GRF file has problem”或游戏数据校验错误

1. 关闭游戏并按 Retry，或重启补丁程序。
2. 等待补丁程序完成安装校验和修复。
3. 通过补丁程序暂时禁用自定义 Addons 或 Gray Map 修改，然后再次测试。
4. 检查杀毒软件是否移除了某个文件。
5. 确保有足够的可用磁盘空间。
6. 如果修复反复失败，请在新的空文件夹中执行全新安装。

Do not randomly delete GRF files or copy GRFs from another server. The patcher can only safely repair files that belong to the current MuhRO release.

Game starts but displays incorrectly, flickers, is black, or has very low FPS

1. Save Game Setup again.
2. Switch between DirectX 9 and DirectX 7.
3. Test windowed mode and a lower resolution.
4. Make sure the intended GPU is selected.
5. Disable overlays and third-party graphics modifications.
6. Reset any Windows compatibility mode previously applied to Muh.exe.
7. Update the graphics driver.

Change one setting at a time so you can identify which change fixed the problem.

“Rejected from Server. (3)”

1. Close every running MuhRO client.
2. Start the patcher again and sign in with your Master Account e-mail address.
3. Select the intended Game Account in the patcher and launch it from there.
4. Do not enter the Master Account e-mail directly into the old in-game login screen.
5. If necessary, sign out of the patcher and sign in again to obtain a new launch session.

If the error continues, contact support with the game-account name and exact time of the attempt. Never send staff your password or security code.

Client freezes, disconnects or crashes after playing for a while

Before contacting support:

1. Test once without custom Addons, Gray Map modifications or overlay software.
2. Note the map, character action and exact local time when it happened.
3. Check whether the problem occurs on every character or only one character/map.
4. Run the fully patched default client from a clean installation folder.
5. Keep any crash message or automatic crash-report identifier shown by the client.

A single crash does not necessarily require reinstalling the client. Reinstall only after patching, graphics settings, runtimes and antivirus history have been checked.

Patcher issues

Help, I am using Linux

See How To Play on Linux.

Set up Wine and place the Linux patcher in the MuhRO game folder:

Muh Patcher for Linux

If Linux reports that the file is not executable, give it execute permission before starting it. Wine and Linux distributions differ, so include the distribution, Wine version and terminal error when requesting support.

Patcher does not start: incompatible software or architecture error

The default Windows patcher is 64-bit. A 32-bit Windows installation requires the 32-bit patcher:

Muh Patcher 32-bit

Save it as Muh_Patcher.exe inside the game folder. A 32-bit patcher is normally not needed on 64-bit Windows.

For Windows 7 64-bit, use the dedicated legacy version:

Muh Patcher for Windows 7 64-bit

Windows 7 and Windows 8.1 are obsolete operating systems and may no longer support every modern launcher component.

Patcher starts as a process but no window or update prompt appears

A patcher pinned directly to the Windows taskbar may hide its update prompt.

1. Open Task Manager and end every Muh_Patcher.exe and updater.exe process.
2. Start Muh_Patcher.exe directly from the game folder.
3. If a hidden update prompt may be active, press Enter once.
4. Remove the old pinned taskbar entry.
5. After the updated patcher starts successfully, create a normal desktop shortcut or pin the new executable again.

Patcher update fails, repeats the update prompt, or cannot replace itself

1. Close the game and all patcher/updater processes through Task Manager.
2. Start the patcher directly from the game folder rather than an old taskbar shortcut.
3. Verify that the game folder is writable and is not inside Program Files, Downloads or OneDrive.
4. Check antivirus Protection History.
5. Retry the update once.

If the automatic update still fails, download the correct patcher manually:

• Windows 64-bit, default
• Windows 32-bit
• Windows 7 64-bit
• Linux

Save the file into the game folder and replace the existing Muh_Patcher.exe. Make sure the browser did not save it under a name such as Muh_Patcher (1).exe.

Patcher opens but the page is blank or the embedded browser fails

The current patcher uses Microsoft Edge WebView2, not Internet Explorer.

1. Close all patcher processes.
2. Install or repair the Microsoft Edge WebView2 Runtime.
3. If the error says WebView2 is already installed, open %LOCALAPPDATA%\MuhRO\Patcher.
4. Rename the WebView2 folder to WebView2.old.
5. Start the patcher again. A fresh WebView2 profile will be created.

If this works, the renamed cache may be removed later. If it does not work, keep it until troubleshooting is complete.

Patching fails with an error in the bottom status bar

Copy or screenshot the complete bottom-bar message. The final part of the error is often the most useful part.

“Connection closed before message end” or another download error

1. Retry once.
2. Check the internet connection and make sure the computer's date and time are correct.
3. Temporarily disconnect from VPN or proxy software.
4. Do not repeatedly use Reset All Patches.
5. If the same file repeatedly fails, try a different network as a diagnostic test.
6. If patch data was reset and cannot be restored, download a fresh full client.

“Failed to get/take the update lock”

Another patcher process, folder permissions or an unsuitable installation path may prevent patching.

1. Close Muh.exe, Muh_Patcher.exe and updater.exe through Task Manager.
2. Restart Windows if the lock remains.
3. Move or reinstall MuhRO into a simple folder such as C:\Games\MuhRO.
4. Avoid spaces, special symbols, protected Windows folders and cloud-synchronized folders.

Running permanently as Administrator is not the preferred solution. A normal user-writable game folder is safer and avoids most permission problems.

MuhVault verification, manifest-signature, or signed-file error

1. Close the game and patcher completely.
2. Check antivirus Protection History for a file removed from the MuhRO folder.
3. Start the official patcher again and allow it to retry verification.
4. Do not delete GRFs, manifest files or signatures at random.
5. Do not download replacement DLL or GRF files from third-party websites.
6. If the same verification error remains, take a screenshot and perform a clean installation into a new folder.

Keep the old folder until the new installation works or staff has collected the required file information.

Security-code or login page error

1. Confirm that Windows date, time and time zone are set automatically.
2. Restart the patcher instead of refreshing the login repeatedly.
3. Disable VPN or proxy software temporarily.
4. Check that the firewall is not blocking Muh_Patcher.exe.
5. Install or repair Microsoft Edge WebView2 if the login page itself does not load.

Do not reset Internet Explorer; it is not used by the current patcher.

Antivirus and Windows Security

Security software may occasionally quarantine the patcher or a required game file because patchers download, verify and replace executable files.

A detection should not automatically be assumed to be harmless. Only restore a file when:

• MuhRO was downloaded from the official website or patcher;
• the detected path is inside the expected MuhRO installation;
• the filename matches the file reported missing by the patcher.

Restoring a MuhRO file from Microsoft Defender

1. Open Windows Security.
2. Select Virus & threat protection.
3. Open Protection history.
4. Select the MuhRO detection and verify its original path.
5. If you are confident it is the official MuhRO file, choose Restore or Allow on device.
6. Start Muh_Patcher.exe and retry patching so the installation is verified again.

If Defender removes the file again, an exception for the exact MuhRO folder may be required. Add only the specific game folder, not an entire drive or a broad folder such as C:\Games.

Do not disable antivirus or firewall protection completely.

Controlled Folder Access blocks the patcher

Windows Controlled Folder Access may block applications from modifying protected folders such as Desktop or Documents.

Moving MuhRO to C:\Games\MuhRO is normally preferable. Alternatively, allow the official Muh_Patcher.exe through Controlled Folder Access after checking its location.

Network and connection problems

1. Check the homepage or announcements for known maintenance.
2. Ensure Windows date and time are correct.
3. Restart the patcher and network connection.
4. Temporarily disable VPN or proxy software.
5. Allow the patcher through the firewall instead of disabling the firewall.
6. Try a different network or mobile hotspot only as a diagnostic test.
7. If one connection works and another does not, tell support which internet provider and country are affected.

Do not open router ports for MuhRO unless staff provides a specific documented reason.

Clean reinstall

Use a clean reinstall only after the simpler steps above have failed.

1. Close all MuhRO and patcher processes.
2. Rename the current folder to something such as MuhRO-old. Do not delete it yet.
3. Download the latest full client from the official MuhRO website.
4. Extract or install it into a new empty folder such as C:\Games\MuhRO.
5. Start the new patcher and let it finish completely.
6. Run Game Setup, save the settings and test the unmodified client.
7. Add custom maps or addons back one at a time only after the default client works.

Do not install a fresh client over a damaged or heavily modified old client. Keep screenshots and personal configuration files in the old folder until the new installation has been tested.

What not to do

• Do not start Muh.exe directly.
• Do not download missing DLL, EXE or GRF files from third-party file websites.
• Do not disable antivirus or firewall protection completely.
• Do not randomly delete GRFs, manifests, signatures or patch files.
• Do not combine files from different private servers.
• Do not repeatedly reset all patches unless instructed.
• Do not send anyone your password, security code or login token.
