- Product
- Google Workspace Sync for Microsoft Outlook
- Device & OS
- Windows 11
- Scenario
- Attempting to install or reinstall Google Workspace Sync for Outlook after a recent Windows 11 upgrade (such as version 24H2).
- Observed behavior
- The GWSMO installation crashes or fails with a Windows Installer package error, often caused by conflicting Google Update components or OS compatibility issues.
Ensure you have administrative privileges on your Windows 11 computer to modify program files and registry keys, and create a system restore point before making any changes.
Uninstall Chrome and Clear Google Directories
Removing existing Google components clears the conflicting Google Update service, allowing the GWSMO installer to run successfully.
This method resolves conflicting background services by completely wiping out old Google registry keys and update folders before attempting to install GWSMO again.
Open the Windows Control Panel, navigate to Programs and Features, locate Google Chrome, and uninstall it.
Open File Explorer (Win + E), navigate to C:\Program Files (x86)\, and permanently delete the folder named 'Google'.
Press Win + R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\ and delete the 'Google' key.
Locate your downloaded gsync.msi file and double-click it to successfully install Google Workspace Sync for Microsoft Outlook.
Once the sync tool is installed, download the latest version of Google Chrome from the official website and reinstall it.

Check Windows 11 Version Compatibility
Verify if your specific version of Windows 11 (such as 24H2) is currently supported by the Google Workspace Sync tool.

Frequently Asked Questions
Why does GWSMO fail to install on Windows 11 24H2?
Google Workspace Sync has known compatibility issues with certain major Windows 11 upgrades, specifically version 24H2. These updates can disrupt the Google Update service or conflict with the Windows Installer, leading to installation failures.
