If you're experiencing issues with uninstalling or installing Microsoft Office 365 due to Click-to-Run errors, here are some steps you can take:

1. Check for Click-to-Run Installation: First, ensure that you have Microsoft Office Click-to-Run installed. You can check this by clicking the File tab in any Office app, then selecting Help. If you see a Click-to-Run Product Updates section, Click-to-Run is installed.
2. Uninstall Click-to-Run: If you need to uninstall Click-to-Run, follow these steps:
   • Click Start, then go to Control Panel.
   • Click on Programs and Features.
   • Find Microsoft Office Click-to-Run in the list, select it, and click Uninstall.
   • Confirm the uninstallation when prompted.
3. Use the Microsoft 365 Uninstall Troubleshooter: If the standard uninstallation process fails, you can use the Microsoft 365 Uninstall troubleshooter. This tool can help remove Office products that are not uninstalling correctly. Make sure to run it on the same device where Office is installed.
4. Repair Office: If you can access the Office apps but they are not functioning correctly, try repairing them:
   • Go to Control Panel > Programs and Features.
   • Select Microsoft Office 365, then click Change.
   • Choose Repair and follow the prompts.
5. Check for Errors: If you encounter specific error codes during installation or uninstallation, look them up for targeted troubleshooting steps. For example, error codes like 30010-45 or 30088-26 can indicate issues with FSLogix settings or other conflicts.
6. Run System File Checker: Since you already ran sfc /scannow, ensure that your system files are intact. If issues persist, consider checking the Windows Event Log service to ensure it's running properly.

If these steps do not resolve the issue, you may need to consider reinstalling Windows or seeking further assistance from Microsoft support.

Hi Matt,

If you are having problems uninstalling or fixing Office 365 Click-to-Run, here are some things to try:

Get a Non-Click-to-Run Version: If Click-to-Run is a headache, grab an Office version with a regular installer (MSI). Look for this in your Microsoft account’s advanced download settings. Big companies tend to use MSI for Office Professional Plus.

Turn Off Click-to-Run Service: If Click-to-Run messes with installing or uninstalling, turn it off. Go to Services (type services.msc in Run), find “Microsoft Office ClickToRun Service, choose Disabled for Startup type, and restart your computer. This can stop issues when fixing things.

Try Office Deployment Tool (ODT): For more control, get the Office Deployment Tool from Microsoft. You can set up how Office installs, pick what parts to install, and change the install type. Great for IT people or anyone who wants a clean install with no old files left behind.

Go for Volume Licensing (MSI Installer): If Click-to-Run often fights with other MSI apps (like Access Runtime), think about getting a volume-licensed Office version that uses MSI install. This keeps Click-to-Run from messing with MSI stuff.

Clean Up Registry and Old Files: Sometimes old registry stuff or Office files stop new installs. Use Microsoft’s Support and Recovery Assistant or manually clean Office-related registry keys after uninstalling. This makes sure everything is fresh for a new install.

Let me know what happens.

Best,
