Old Version of Office Still Showing After Fresh Installation

Download and install Geek Uninstaller (portable version available):
- Open Geek Uninstaller
- Search for Microsoft Office
- Right-click and select "Force Removal"
- Restart your computer after uninstallation
If traces remain after using Geek Uninstaller:
- Delete the C:\Program Files\Microsoft Office folder
- Remove Office entries from Registry Editor (advanced users only)
- Clear temporary files using Disk Cleanup
After complete removal, restart your computer before attempting to install the new version of Office.
Critical Removal of KMS/Pirated Licenses
Warning: Systems with previously installed KMS activators or pirated licenses may require special removal procedures. These unauthorized activations can prevent proper installation of genuine licenses.
Follow these steps to completely remove illegitimate Office installations:
After successfully removing all unwanted licenses, restart your computer before attempting to install genuine Office software.
Office 365 Account Setup Error
This common Office 365 error typically occurs when previous installations weren't properly cleaned or when there were issues during setup.
- Click "Done" on the error message

Update Channel Installation Error
This error occurs when there's a mismatch between your Office version and the update channel. Follow these steps to resolve:
- Press Windows Key + R, type regedit and press Enter
- Enable the Address Bar (View > Address Bar)
- Paste this path in the Address Bar and press Enter:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun
- Check for a sub-folder named Configuration
- If present, right-click the Configuration key and select Delete
- Restart your computer (not just shutdown)
- Attempt the Office installation again
Note: Editing the registry can affect system stability. Consider creating a backup before making changes.
Understanding Office License Types
All Office license types provide the same features and functionality. The differences lie in activation methods and transferability:
- Instant internet activation
- Single machine activation
- No transferability
- Ideal for users with consistent internet
- Requires phone call activation
- Works without persistent internet
- Single machine activation
- Good for limited internet access
- Linked to Microsoft account
- Transferable between devices
- Simplified reinstallation
- Best for users with multiple devices
Tip: Email-bound licenses offer the most flexibility as they're tied to your Microsoft account rather than a specific device.
