The error 'Error 1920. Service 'Office Software Protection Platform' (osppsvc) failed to start.' occurs when attempting to install Microsoft Office 2010 on a Windows 7 Professional machine, using an administrator account. This issue can be frustrating for users who rely on Microsoft Office for their work or personal projects. In this guide, we will walk through the steps to troubleshoot and resolve this error.

The error 'Error 1920. Service 'Office Software Protection Platform' (osppsvc) failed to start.' is often caused by a problem with the Office Software Protection Platform service, which is responsible for protecting Microsoft Office installations from unauthorized use. If you have tried the recommended fixes provided by Microsoft and are still experiencing issues, do not worry - we will explore alternative solutions in this guide.

💡 Why You Are Getting This Error

  • The primary reason for this error is a misconfigured or non-existent 'Network Service' account in the Windows Local Users and Groups. When the Office Software Protection Platform service tries to start, it looks for the 'Network Service' account to log on as, but if it does not exist or is incorrectly configured, the service fails to start. This can occur due to a variety of reasons, such as an outdated or corrupted group policy, a misconfigured user account, or a problem with the Windows operating system.
  • An alternative reason for this error could be a conflict between the Office Software Protection Platform service and another service on the system. In some cases, other services may interfere with the Office Software Protection Platform service, causing it to fail to start. This can occur if there are multiple services running simultaneously, or if one of the services is not properly configured.

🔧 Proven Troubleshooting Steps

Manually configuring the 'Network Service' account

  1. Step 1: Open the Run dialog box by pressing the Windows key + R. Type 'services.msc' and press Enter to open the Services window.
  2. Step 2: In the Services window, right-click on the Office Software Protection Platform service and select Properties.
  3. Step 3: In the Properties window, click on the Log On tab and change the 'Log on as' information from 'This Account' (Network Service) to 'Local System Account'.
  4. Step 4: Click Apply and OK to save the changes. This will update the configuration of the Office Software Protection Platform service to use the Local System Account instead of the Network Service account.

Using the Computer Management console to add the 'Network Service' account

  1. Step 1: Open the Computer Management console by searching for it in the Start menu or typing 'compmgmt.msc' in the Run dialog box.
  2. Step 2: In the Computer Management console, expand System Tools > Local Users and Groups > Groups.
  3. Step 3: Double-click on the Users group and click Add. Click Locations and select your computer node.
  4. Step 4: Type 'Network Service' into the 'Enter the object names' field or click Advanced, then Find Now and select it from the Search Results.
  5. Step 5: If 'Network Service' is already listed as an existing account, you may need to delete and recreate it. To do this, right-click on 'Network Service' and select Delete. Then, repeat the steps above to add the new account.

✨ Wrapping Up

By following these steps, you should be able to resolve the error 'Error 1920. Service 'Office Software Protection Platform' (osppsvc) failed to start.' and successfully install Microsoft Office 2010 on your Windows 7 Professional machine.
