3 easy Ways to Activate Office 2019 Without Product Key

Microsoft Office is an essential tool for many professionals, students, and businesses. However, activating it can sometimes be a challenge, especially when you don’t have a product key. In this article, we’ll explore various ways to activate Office 2019 without a product key.

Understanding Office 2019 Activation

Activation is an essential step when installing Microsoft Office 2019 on your computer. It is a process that verifies that the software you installed is genuine and has been licensed for use by Microsoft. Without activation, you will not be able to use Office 2019 beyond the initial trial period. In this section, we will provide a comprehensive overview of the activation process and the importance of activation for using Office 2019.

When you install Office 2019, you have a 30-day trial period during which you can use the software without activating it. However, after the trial period expires, you will need to activate the software to continue using it. Activation requires a valid product key that comes with your purchase. The product key is a unique code that identifies your copy of Office 2019 and is used to activate it.

Activation is a crucial step for ensuring the security and authenticity of your Office 2019 software. It ensures that the software you are using is genuine and not a pirated or counterfeit version. It also helps Microsoft to prevent software piracy, which can result in significant financial losses for the company.

In summary, understanding the activation process for Office 2019 is essential for ensuring that you can use the software effectively and without interruptions. Activating your copy of Office 2019 with a valid product key ensures that you have access to all the features and updates that the software offers, while also helping to protect you from security threats associated with pirated or counterfeit software.

Method 1: Use KMS client key

One way to activate Office 2019 without a product key is to use a KMS (Key Management Service) client key. These keys are publicly available and allow you to activate Office 2019 on a local network without the need for a product key. However, this method is only suitable for businesses that have an active KMS host server.

Step 1: Open Command Prompt in Administrator Mode

To begin, you’ll need to open Command Prompt with administrator rights. Simply search for “Command Prompt” in your Windows search bar, right-click on it, and select “Run as administrator“.

Step 2: Open the Location of Office Installed on Your PC

cd /d %ProgramFiles%\Microsoft Office\Office16
cd /d %ProgramFiles(x86)%\Microsoft Office\Office16

Once Command Prompt is open, you’ll need to navigate to the location where your Office is installed on your PC. If you installed Office in the ProgramFiles folder, the path will be “%ProgramFiles%\Microsoft Office\Office16” or “%ProgramFiles(x86)%\Microsoft Office\Office16” depending on the architecture of your Windows OS. If you’re not sure, simply run both commands and one of them will execute successfully while the other will show an error message.

Step 3: Convert Your Retail License to Volume One

for /f %x in ('dir /b ..\root\Licenses16\ProPlus2019VL*.xrm-ms') do cscript ospp.vbs /inslic:"..\root\Licenses16\%x"

If you obtained your Office from Microsoft, this step is required. However, if you installed Office from a Volume ISO file, you can skip this step.

Step 4: Activate Your Office Using KMS Client Key

Make sure your PC is connected to the internet, and then run the following command in Command Prompt:

cscript ospp.vbs /setprt:1688 
cscript ospp.vbs /unpkey:6MWKP >nul 
cscript ospp.vbs /inpkey:NMMKJ-6RK4F-KMJVX-8D9MJ-6MWKP 
cscript ospp.vbs /sethst:e8.us.to 
cscript ospp.vbs /act

If you receive the error code “0xC004F074”, it means that your internet connection is unstable or the server is busy. Ensure your device is online and try the command “act” again until you successfully activate your Office.

That’s it! Once you receive the message “Office activated successfully” in Command Prompt, your Microsoft Office software is ready to use on your PC. By following these simple steps, you can ensure that your Office is properly activated and avoid any potential issues down the road.

Method 2: Use code

Another method to activate Office 2019 is by using code. This method involves copying and pasting a script into a command prompt window, which triggers the activation process. This method is suitable for individuals who don’t have access to a KMS host server.

Step 1: Right-click on your desktop and select “New” and then “Text Document” to create a new text document.

Step 2: Copy the following code into a new text document.
