How to Fix OSPPREARM.exe Failed to Activate Issue Microsoft Office

What is OSPPREARM.exe and why does it fail to activate Microsoft Office?

OSPPREARM.exe is a tool that allows you to extend the trial period of Microsoft Office without needing a proper license for immediate activation. Essentially, it acts as a temporary solution by resetting the activation status of Office products, enabling continued use during the trial period. This can be a more cost-effective option to test out Microsoft Office if you’re not ready to purchase a full license yet.

However, when OSPPREARM.exe fails, it can leave you in a state of confusion prompting you to think how to fix annoying OSPPREARM.exe errors? Before diving in on how to activate OSPPREARM.exe, let’s first investigate the common reasons why you may encounter the OSPPREARM.exe failed error:

  • Corrupted Installation Files: If the installation files for Microsoft Office were not properly downloaded or became corrupted during the installation process, the OSPPREARM.exe tool may fail to execute.

  • Expired Trial Period: OSPPREARM.exe is meant to reset the activation status during the trial period. If the trial has fully expired, the tool will no longer be able to extend the usage.

  • Permission Issues: Sometimes, the tool fails to run due to insufficient administrative privileges. OSPPREARM.exe requires elevated permissions to make changes to the Office activation status.

  • Outdated or Incompatible Software: Using an outdated version of Microsoft Office or a version that is incompatible with your operating system can lead to the failure of OSPPREARM.exe.

  • Interference from Other Software: Antivirus programs or system security settings may block the execution of OSPPREARM.exe, mistaking it for malicious activity.

Step 2: Once downloaded and installed, select the option related to activation issues and follow the prompts to diagnose and fix problems with your Microsoft Office activation.

Tip 4: Repair or Reinstall Microsoft Office

If nothing has worked so far, it might be due to some corrupted files. In this case, it's best to repair Microsoft Office first. If the problem persists, I suggest reinstalling the application to get a fresh start.

Step 1: Open the Control Panel on your system and go to the "Uninstall a Program" section.

Note: The appearance of this window may differ depending on your version of Windows.

Step 2: Locate your Microsoft Office product, right-click on it, and select "Change" from the context menu.

Step 5: If the Quick Repair does not fix the issue, try performing a full "Online Repair" for a more thorough solution.

If the OSPPREARM.exe file still isn’t running after the repair, try reinstalling the Office suite.

Step 1: In the Control Panel, find Microsoft Office, right-click on it, and select "Uninstall" to remove the suite from your system.

Step 2: Once Office is uninstalled, go to the official Microsoft website using your browser.

Step 3: Sign in to your Microsoft account and download the Office suite compatible with your Windows version.

Step 4: After downloading, install the Office suite. Open any Office application, sign in, and start using the software.

Tip 5: Manual Activation

If after reinstallation, your Office suite still isn’t activating and continues showing the activation error, try using your product key to manually activate Microsoft Office.

Step 1: Launch any Microsoft application on your computer, such as Microsoft Word, to open the Activation Wizard.

Step 2: On the startup page of the Microsoft app, navigate to the "Account" tab on the left sidebar.

Step 3: In the Account section, locate and click the "Activate Product" button positioned centrally on the page.

Tip 6: Check the Time and Date on Your Computer

When the date and time on your computer are not set correctly, it can interfere with the activation process because Microsoft Office relies on accurate time settings to verify licenses and connect with its activation servers. Therefore, make sure the date and time on your computer are accurate.

Step 1: Press the “Windows” key on your keyboard and go to “Settings”.

Step 2: In the Settings window, click on the “Time & Language” tab on the left pane.

Step 3: Under Time & Language, make sure the “Set time automatically” option is toggled on.
