<span id="MuhRO_Troubleshooting"></span>
= Solução de problemas do MuhRO =

A maioria dos problemas pode ser resolvida sem reinstalar o Windows ou desativar o software de segurança. Siga os passos abaixo na ordem e pare quando o problema for resolvido.

<span id="Before_you_begin"></span>
== Antes de começar ==

# Feche <code>Muh.exe</code>, <code>Muh_Patcher.exe</code> e <code>updater.exe</code>. Use o Gerenciador de Tarefas se algum deles continuar aberto.
# Reinicie o computador se o Windows, um driver de vídeo ou um runtime tiver sido atualizado recentemente.
# Inicie <code>Muh_Patcher.exe</code> na pasta do jogo MuhRO. Não inicie <code>Muh.exe</code> diretamente.
# Deixe o patcher terminar a atualização antes de pressionar Play.
# Abra o '''Game Setup''', selecione suas configurações de vídeo e pressione '''Save''' pelo menos uma vez.
# Se aparecer um erro, guarde o texto exato ou tire um print antes de fechá-lo.

<span id="Recommended_installation_folder"></span>
=== Pasta de instalação recomendada ===

Instale ou extraia o MuhRO em uma pasta curta e local, como:

<code>C:\Games\MuhRO</code>

Evite instalar o jogo em:

* <code>C:\Program Files</code> ou <code>C:\Program Files (x86)</code>;
* os diretórios Windows ou System32;
* Downloads, Área de Trabalho ou Documentos;
* OneDrive ou outra pasta sincronizada na nuvem;
* uma unidade de rede;
* uma pasta com letras que não sejam do inglês, símbolos especiais ou um caminho excepcionalmente longo.

Recomenda-se um caminho usando apenas letras latinas normais e números. Não execute o patcher de dentro de um arquivo ZIP; extraia o cliente completo primeiro.

<span id="Client_issues"></span>
== Problemas do cliente ==

<span id="Client_does_not_start,_closes_without_an_error,_reports_an_MSVCP/VCRUNTIME_DLL_error,_or_crashes_randomly"></span>
=== O cliente não inicia, fecha sem erro, relata um erro de DLL MSVCP/VCRUNTIME ou trava aleatoriamente ===

Tente estes passos:

# Inicie o patcher e certifique-se de que todas as atualizações sejam concluídas.
# Execute o '''Game Setup''', escolha uma resolução normal e salve as configurações.
# Instale os dois Microsoft Visual C++ Redistributables atuais:
#* [https://aka.ms/vc14/vc_redist.x86.exe Visual C++ x86]
#* [https://aka.ms/vc14/vc_redist.x64.exe Visual C++ x64]
# Reinicie o Windows depois de instalar ou reparar os runtimes.
# Feche temporariamente softwares que injetam overlays em jogos, como overlays de gravação, ReShade, RTSS ou ferramentas semelhantes.
# Atualize o driver de vídeo diretamente da Intel, AMD ou NVIDIA.
# Verifique o Histórico de Proteção da Segurança do Windows ou do seu antivírus para ver se há arquivos removidos da pasta do MuhRO.

O runtime x86 do Visual C++ é necessário para o cliente de jogo de 32 bits, inclusive no Windows de 64 bits. Não baixe arquivos DLL individuais de sites de download de DLL.

<span id="Blank_error_when_starting_the_client"></span>
=== Erro em branco ao iniciar o cliente ===

[[File:blank.png]]

Isso costuma acontecer quando <code>Muh.exe</code> é iniciado diretamente. Sempre inicie <code>Muh_Patcher.exe</code>, faça login e abra a conta de jogo selecionada pelo patcher.

<div lang="en" dir="ltr" class="mw-content-ltr">
Open '''Game Setup''' in the patcher and try the following:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Select '''DirectX 9''' and save the settings.
# If DirectX 9 does not work, test '''DirectX 7'''.

<div lang="en" dir="ltr" class="mw-content-ltr">

# Test once without custom Addons, Gray Map modifications or overlay software.
# Note the map, character action and exact local time when it happened.

# Run the fully patched default client from a clean installation folder.
# Keep any crash message or automatic crash-report identifier shown by the client.

<div lang="en" dir="ltr" class="mw-content-ltr">
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 ==
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Help, I am using Linux ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
See [[How To Play on Linux]].
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Set up Wine and place the Linux patcher in the MuhRO game folder:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
[https://patcher.muhro.eu/patches/patcher/linux/Muh_Patcher Muh Patcher for Linux]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
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.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Patcher does not start: incompatible software or architecture error ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The default Windows patcher is 64-bit. A 32-bit Windows installation requires the 32-bit patcher:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
[https://patcher.muhro.eu/patches/patcher/32/Muh_Patcher.exe Muh Patcher 32-bit]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Save it as <code>Muh_Patcher.exe</code> inside the game folder. A 32-bit patcher is normally not needed on 64-bit Windows.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
For Windows 7 64-bit, use the dedicated legacy version:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
[https://patcher.muhro.eu/patches/patcher/win7/Muh_Patcher.exe Muh Patcher for Windows 7 64-bit]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Windows 7 and Windows 8.1 are obsolete operating systems and may no longer support every modern launcher component.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Patcher starts as a process but no window or update prompt appears ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
A patcher pinned directly to the Windows taskbar may hide its update prompt.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Open Task Manager and end every <code>Muh_Patcher.exe</code> and <code>updater.exe</code> process.
# Start <code>Muh_Patcher.exe</code> directly from the game folder.
# If a hidden update prompt may be active, press Enter once.
# Remove the old pinned taskbar entry.
# After the updated patcher starts successfully, create a normal desktop shortcut or pin the new executable again.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Patcher update fails, repeats the update prompt, or cannot replace itself ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Close the game and all patcher/updater processes through Task Manager.
# Start the patcher directly from the game folder rather than an old taskbar shortcut.
# Verify that the game folder is writable and is not inside Program Files, Downloads or OneDrive.
# Check antivirus Protection History.
# Retry the update once.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If the automatic update still fails, download the correct patcher manually:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* [https://patcher.muhro.eu/patches/patcher/64/Muh_Patcher.exe Windows 64-bit, default]

* [https://patcher.muhro.eu/patches/patcher/win7/Muh_Patcher.exe Windows 7 64-bit]
* [https://patcher.muhro.eu/patches/patcher/linux/Muh_Patcher Linux]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Save the file into the game folder and replace the existing <code>Muh_Patcher.exe</code>. Make sure the browser did not save it under a name such as <code>Muh_Patcher (1).exe</code>.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Patcher opens but the page is blank or the embedded browser fails ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The current patcher uses Microsoft Edge WebView2, not Internet Explorer.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Close all patcher processes.
# Install or repair the [https://developer.microsoft.com/en-us/microsoft-edge/webview2/ Microsoft Edge WebView2 Runtime].
# If the error says WebView2 is already installed, open <code>%LOCALAPPDATA%\MuhRO\Patcher</code>.
# Rename the <code>WebView2</code> folder to <code>WebView2.old</code>.
# Start the patcher again. A fresh WebView2 profile will be created.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If this works, the renamed cache may be removed later. If it does not work, keep it until troubleshooting is complete.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Patching fails with an error in the bottom status bar ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Copy or screenshot the complete bottom-bar message. The final part of the error is often the most useful part.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== “Connection closed before message end” or another download error ====
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Retry once.
# Check the internet connection and make sure the computer's date and time are correct.
# Temporarily disconnect from VPN or proxy software.
# Do not repeatedly use Reset All Patches.
# If the same file repeatedly fails, try a different network as a diagnostic test.
# If patch data was reset and cannot be restored, download a fresh full client.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== “Failed to get/take the update lock” ====
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Another patcher process, folder permissions or an unsuitable installation path may prevent patching.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Close <code>Muh.exe</code>, <code>Muh_Patcher.exe</code> and <code>updater.exe</code> through Task Manager.
# Restart Windows if the lock remains.
# Move or reinstall MuhRO into a simple folder such as <code>C:\Games\MuhRO</code>.
# Avoid spaces, special symbols, protected Windows folders and cloud-synchronized folders.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Running permanently as Administrator is not the preferred solution. A normal user-writable game folder is safer and avoids most permission problems.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== MuhVault verification, manifest-signature, or signed-file error ====
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Close the game and patcher completely.
# Check antivirus Protection History for a file removed from the MuhRO folder.
# Start the official patcher again and allow it to retry verification.
# Do not delete GRFs, manifest files or signatures at random.
# Do not download replacement DLL or GRF files from third-party websites.
# If the same verification error remains, take a screenshot and perform a clean installation into a new folder.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Keep the old folder until the new installation works or staff has collected the required file information.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Security-code or login page error ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Confirm that Windows date, time and time zone are set automatically.
# Restart the patcher instead of refreshing the login repeatedly.
# Disable VPN or proxy software temporarily.
# Check that the firewall is not blocking <code>Muh_Patcher.exe</code>.
# Install or repair Microsoft Edge WebView2 if the login page itself does not load.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Do not reset Internet Explorer; it is not used by the current patcher.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
== Antivirus and Windows Security ==
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Security software may occasionally quarantine the patcher or a required game file because patchers download, verify and replace executable files.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
A detection should not automatically be assumed to be harmless. Only restore a file when:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* 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.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Restoring a MuhRO file from Microsoft Defender ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Open '''Windows Security'''.
# Select '''Virus & threat protection'''.
# Open '''Protection history'''.
# Select the MuhRO detection and verify its original path.
# If you are confident it is the official MuhRO file, choose '''Restore''' or '''Allow on device'''.
# Start <code>Muh_Patcher.exe</code> and retry patching so the installation is verified again.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
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 <code>C:\Games</code>.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Do not disable antivirus or firewall protection completely.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Controlled Folder Access blocks the patcher ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Windows Controlled Folder Access may block applications from modifying protected folders such as Desktop or Documents.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Moving MuhRO to <code>C:\Games\MuhRO</code> is normally preferable. Alternatively, allow the official <code>Muh_Patcher.exe</code> through Controlled Folder Access after checking its location.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
== Network and connection problems ==
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Check the homepage or announcements for known maintenance.
# Ensure Windows date and time are correct.
# Restart the patcher and network connection.
# Temporarily disable VPN or proxy software.
# Allow the patcher through the firewall instead of disabling the firewall.
# Try a different network or mobile hotspot only as a diagnostic test.
# If one connection works and another does not, tell support which internet provider and country are affected.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Do not open router ports for MuhRO unless staff provides a specific documented reason.
</div>

# Close all MuhRO and patcher processes.
# Rename the current folder to something such as <code>MuhRO-old</code>. Do not delete it yet.
# Download the latest full client from the official MuhRO website.
# Extract or install it into a new empty folder such as <code>C:\Games\MuhRO</code>.
# Start the new patcher and let it finish completely.
# Run Game Setup, save the settings and test the unmodified client.
# 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.
