Microsoft Office 2016 Professional Plus must be activated using a valid, legitimate product key. Below, you will find complete activation methods: via the graphical interface, command line, and by phone. This guide applies to the installation of the Office 2016 package on the Windows system.

This guide describes only official activation methods. Do not use unauthorized activators, license modifications, or security bypass tools.

Before You Start

Prepare:

• A 25-character product key for Microsoft Office 2016 Professional Plus
• Administrator privileges in the Windows system
• An internet connection for online activation
• The phone activation number: 00 800 121 1654

The most common locations of the ospp.vbs file:

C:\Program Files\Microsoft Office\Office16

C:\Program Files\root\Office16

If you have a 64-bit system with 32-bit Office, also check:

C:\Program Files (x86)\Microsoft Office\Office16
C:\Program Files (x86)\root\Office16

Method 1: Activation via Graphical Interface

This is the simplest method for most users.

1. Run any Office package program, such as Word 2016 or Excel 2016.
2. Click File.
3. Go to the Account section.
4. If the package is not activated, select Activate Product or Change Product Key.
5. Enter your 25-character key.
6. Confirm and wait for the activation to complete.

After successful activation, in the File > Account section, you should see a message like:

• Product activated
• Microsoft Office Professional Plus 2016
• Licensed product

Method 2: Activation via CMD using ospp.vbs

This method is useful when activation via GUI does not work or you want to check the license status more thoroughly.

Open Command Prompt as Administrator, then navigate to the Office 2016 directory.

Variant 1: Classic Path

cd /d "C:\Program Files\Microsoft Office\Office16"

Variant 2: root Path

cd /d "C:\Program Files\root\Office16"

Then, enter the product key:

cscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

After saving the key, run the activation:

cscript ospp.vbs /act

If the command is successful, you will see a message about successful activation.

Verification Commands

After activation, check the license status:

cscript ospp.vbs /dstatus

More detailed information about installed licenses:

cscript ospp.vbs /dstatusall

Check the last 5 characters of the installed product key:

cscript ospp.vbs /dstatus

In practice, pay attention to the fields:

• LICENSE NAME
• LICENSE STATUS
• Last 5 characters of installed product key

The correct result should contain a status similar to:

LICENSE STATUS:  ---LICENSED---
