Use the Microsoft Support and Recovery Assistant (SaRA)
The most effective method to forcibly remove a deeply corrupted Office installation that causes the c2r64.dll error when standard uninstallation fails.
The c2r64.dll file is a critical component of Microsoft Office's Click-to-Run technology. When it becomes deeply corrupted or blocked by conflicting installations, standard Windows removal tools will not work.
The Microsoft Support and Recovery Assistant bypasses the standard uninstaller to clean out broken registry keys and stubborn installation files.
Navigate to the official Microsoft website and download the Microsoft Support and Recovery Assistant (SaRA) executable file to your computer.
Double-click the downloaded SetupProd_OffScrub.exe file and click 'Install' to set up the application. Agree to the Microsoft Services Agreement when prompted.
Launch the application, select 'Office' from the list of programs having issues, and then click 'Next'. Choose the option indicating you have Office installed but cannot uninstall it.
Select the specific version of Microsoft Office you want to remove and click 'Next'. Follow the remaining on-screen prompts to allow the tool to scrub the installation.
Once the tool confirms the uninstallation is complete, restart your Windows computer. After rebooting, log back into your Microsoft account and reinstall Office from scratch.

Frequently Asked Questions
What is the c2r64.dll file in Windows?
The c2r64.dll file is a vital 'Click-to-Run' component used by Microsoft Office to stream, update, and launch Office applications. If this file is missing, damaged, or blocked by the operating system, Word, Excel, and other Office programs will fail to start.
Can I download the missing c2r64.dll file from a third-party website?
It is highly recommended not to download standalone DLL files from unverified third-party websites. These files can contain malware, or they might be the wrong version, which can cause further system instability. Always use official Microsoft repair tools instead.
Why do standard uninstall methods fail when this error occurs?
Standard Windows uninstall routines rely on the very installation components that might be broken (like the c2r64.dll file). When these core components are corrupted or when multiple Office versions create conflicts, the standard 'Add or Remove Programs' tool is blocked, requiring the specialized Support and Recovery Assistant.
