Office C2R Custom Installation: Explained & Activated with MAS

Office C2R Custom Installation

Microsoft Office is an indispensable suite of productivity tools for millions worldwide. While many users opt for the standard installation, there's a powerful, often underutilized feature called "Office C2R Custom Installation." This capability allows you to precisely control which Office applications are installed, tailoring the suite to your specific needs and optimizing system resources. No more bloatware or unwanted applications taking up valuable space.

What is Office C2R Custom Installation?

C2R stands for "Click-to-Run," which is Microsoft's modern installation technology for Office products, replacing the older MSI-based installations. Unlike traditional setups that often install the entire suite by default, C2R custom installation empowers users to select individual applications (e.g., Word, Excel, PowerPoint, Outlook, Access, Publisher, OneNote, Teams, etc.) they wish to deploy. It also allows for granular control over language packs, update channels, and even the removal of specific components after installation.

This level of customization is particularly beneficial for several reasons:

• Resource Optimization: Installing only what you need reduces disk space usage and can potentially improve system performance by minimizing background processes.
• Workflow Streamlining: For users who only ever use Word and Excel, installing the full suite including Access, Publisher, and Outlook can be distracting and unnecessary.
• Managed Environments: IT administrators in corporate or educational settings often leverage custom C2R deployments to ensure consistency, enforce policies, and optimize software distribution across numerous machines.
• Faster Installation: With fewer components to download and install, the setup process can be significantly quicker.
• Specific Needs: Some users might only need one specific application, like Project or Visio, without the core Office suite. Custom installation makes this possible.

Traditionally, custom C2R installations are managed using the Office Deployment Tool (ODT), which involves creating a configuration XML file specifying the desired applications, languages, and other settings. This XML file then dictates the behavior of the C2R installer.

How MAS Solves Office C2R Custom Installation Activation

Once you’ve meticulously crafted your custom Office C2R installation, the next crucial step is activation. This is where Microsoft Activation Scripts (MAS) comes into play, offering a robust and reliable solution for permanent activation. MAS supports various activation methods, but for Office C2R, the primary methods leveraged are typically Ohook and Online KMS, ensuring a genuine and lasting activation.

• Ohook Activation: This method is highly effective for Office C2R installations. It works by emulating a genuine activation state, often by patching the Office licensing files. Ohook is known for its persistence and ability to provide a permanent activation without requiring recurring re-activations, making it a 'set-and-forget' solution for many users.
• Online KMS (Key Management Service) Activation: While primarily used in enterprise environments, MAS can utilize publicly available KMS servers or even simulate a KMS server locally to activate Office. This method typically activates Office for 180 days, but MAS includes a scheduled task that automatically renews the activation before it expires, effectively making it a permanent solution.

MAS intelligently detects your Office version and the type of installation (C2R in this case) and applies the most suitable activation method. This means you don't need to be an expert in licensing; MAS handles the intricacies for you. By using MAS, you can ensure your custom Office suite is fully functional without any limitations, allowing you to enjoy the benefits of your tailored installation without interruption.

Step-by-Step Instructions for Custom Office C2R Installation & Activation with MAS

This guide assumes you have already downloaded the Office Deployment Tool (ODT) and created your custom configuration XML file. If not, please refer to Microsoft's documentation on ODT to create your desired custom installation configuration.

Part 1: Custom Office C2R Installation (using ODT)

1. Download Office Deployment Tool (ODT): Go to Microsoft's official website and download the ODT. Run the executable to extract the setup.exe and example configuration XML files to a folder (e.g., C:\OfficeSetup).

2. Create Your Configuration XML: Open one of the sample XML files or create a new one (e.g., custom_config.xml) in your C:\OfficeSetup folder. Edit it to specify the Office applications, version, architecture, and language you want. Here's a basic example for Office LTSC Professional Plus 2021 (64-bit, English) with only Word and Excel:

   <Configuration>
     <Add OfficeClientEdition="64" Channel="PerpetualVL2021">
       <Product ID="ProPlus2021Volume">
         <Language ID="en-us" />
         <ExcludeApp ID="Access" />
         <ExcludeApp ID="Groove" />
         <ExcludeApp ID="Lync" />
         <ExcludeApp ID="OneDrive" />
         <ExcludeApp ID="OneNote" />
         <ExcludeApp ID="Outlook" />
         <ExcludeApp ID="Publisher" />
         <ExcludeApp ID="Teams" />
       </Product>
     </Add>
     <Property Name="SharedComputerLicensing" Value="0" />
     <Property Name="PinIconsToTaskbar" Value="TRUE" />
     <Property Name="AUTOACTIVATE" Value="0" />
     <Property Name="FORCEAPPSHUTDOWN" Value="FALSE" />
     <Property Name="DeviceBasedLicensing" Value="0" />
     <Updates Enabled="TRUE" />
     <Display Level="Full" AcceptEULA="TRUE" />
     <Logging Level="Standard" Path="%temp%" />
   </Configuration>
   

   • Note: Adjust Product ID, Channel, OfficeClientEdition, and ExcludeApp tags according to your specific needs (e.g., Standard2019Volume, Monthly, 32).

3. Download Office Files: Open an Administrator Command Prompt or PowerShell. Navigate to your C:\OfficeSetup directory. Run the command to download the Office installation files: setup.exe /download custom_config.xml

   This process can take some time depending on your internet speed and the size of your selected components.

4. Install Custom Office: Once the download is complete, run the installation command: setup.exe /configure custom_config.xml

   The Office installer will run silently or with a progress bar, installing only the applications you specified.

Part 2: Activating Custom Office C2R Installation with MAS

After your custom Office installation is complete, proceed with activation using MAS:

1. Temporarily Disable Antivirus: Before proceeding, it's crucial to temporarily disable your antivirus software. MAS uses methods that some security programs might mistakenly flag as malicious (a false positive) due to their nature of interacting with system licensing components. The ZIP password for MAS is WYqejXiqBi97.
2. Open PowerShell as Administrator:
   • Press Win + X and select Windows PowerShell (Admin) or Terminal (Admin).
3. Execute the MAS Command: Copy and paste the following command into the PowerShell window and press Enter: irm https://get.activated.win | iex
4. Follow On-Screen Prompts: The script will download and execute the MAS menu. You'll typically see options for Windows and Office activation. Select the option for Office activation. MAS will then automatically detect your custom Office C2R installation and apply the most suitable activation method (Ohook or Online KMS).
5. Verify Activation: Once the script completes, restart your computer (optional but recommended). Open any Office application (e.g., Word), go to File > Account, and check the activation status. It should show as "Product Activated."

Troubleshooting Common Issues

• Antivirus Flags MAS: This is the most common issue. As mentioned, temporarily disable your antivirus before running MAS. Remember to re-enable it after activation is complete.
• "Not Activated" After Running MAS:
  • Ensure PowerShell was run as Administrator.
  • Re-run the MAS script. Sometimes a second attempt resolves transient issues.
  • Check your internet connection if using Online KMS, as it requires reaching a KMS server.
  • Ensure no other activators are running concurrently or have left residual files that conflict with MAS.
• Office Installation Errors (ODT):
  • Incorrect XML Syntax: Double-check your custom_config.xml for typos or incorrect tags. Even a small error can prevent installation.
  • Network Issues: If the download fails, check your internet connection or proxy settings.
  • Permissions: Ensure you're running the Command Prompt/PowerShell as Administrator when executing ODT commands.
  • Conflicting Office Versions: Uninstall any previous Office versions completely before attempting a new custom C2R installation.
• Office C2R Activation Expired (KMS): If you used a KMS activation method and it expired, the MAS script automatically schedules a task for re-activation. If it somehow fails, simply re-run the MAS script: irm https://get.activated.win | iex.
• Office Applications Not Appearing: If your custom installation doesn't show the expected applications, review your ExcludeApp tags in the XML. You might have accidentally excluded an application you intended to install.
