• Multiple Activation Key (MAK) for Office on Windows
• Volume License (VL) Serializer for Office on a Mac

If you’re not a volume licensed customer, follow these instructions.

KMS activation steps for Office on Windows

If you activate Office by using KMS, including Active Directory-based activation, do the following steps to update Office LTSC 2024 Preview to Office LTSC 2024.

1. If you haven't already done so, set up a KMS host computer. If you currently have a Windows KMS host computer on an operating system that supports Office KMS, we recommend that you use the same computer for your Office KMS host computer.
2. Download the Office LTSC 2024 Volume License Pack from the Microsoft Download Center.
3. Sign in to the Microsoft 365 admin center and go to > Billing > Your products > Volume licensing > Downloads & Keys to get your KMS client activation keys for Office LTSC 2024.
4. Configure the KMS host computer to activate Office LTSC 2024. You'll need both the Office LTSC 2024 Volume License Pack and your KMS client activation keys.
5. Make sure that you’re using at least Version 2408 of Office LTSC 2024 Preview. To check your version, open Word, and go to File > Account. Under the About Word section, you’ll see the version and build number.
6. Run the ospp.vbs script on each computer to install and activate your KMS client activation key using the commands below.

cscript ospp.vbs /inpkey:yourkey
cscript ospp.vbs /act

Replace yourkey with your KMS client activation key. You will need to restart any Office apps to see these changes take effect.

If you set up the Office LTSC 2024 KMS Host on a different computer than your Office LTSC 2024 Preview KMS host and you aren't using Active Directory-based activation, then the previous commands might not work, so also try running these commands:

cscript ospp.vbs /remhst
cscript ospp.vbs /sethst:KMSHostFQDN
cscript ospp.vbs /act

Replace KMSHostFQDN with the fully qualified domain name of the Office LTSC 2024 KMS Host computer. You will need to restart any Office apps for these changes to take effect.

MAK activation steps for Office on Windows

If you activate Office by using MAK, do the following steps to update Office LTSC 2024 Preview to Office LTSC 2024.

1. Sign in to the Microsoft 365 admin center and go to > Billing > Your products > Volume licensing > Downloads & Keys to get your MAK client activation keys for Office LTSC 2024.
2. Make sure that you’re using at least Version 2408 of Office LTSC 2024 Preview. To check your version, open Word, and go to File > Account. Under the About Word section, you’ll see the version and build number.
3. Run the ospp.vbs script on each computer to install and activate your MAK client activation key using the commands below.

 cscript ospp.vbs /inpkey:yourkey
 cscript ospp.vbs /act

Replace yourkey with your MAK client activation key. You will need to restart any Office apps for these changes to take effect.

Additional information for Office on Windows

• The ospp.vbs commands can be included in a script that you can deploy and run across the computers in your organization, such as with Microsoft Configuration Manager.
• You can also use the Volume Activation Management Tool (VAMT) 3.1 to centrally manage volume activation. You need to use VAMT 3.1 with Office LTSC 2024. VAMT 3.0 won't work with Office LTSC 2024. For more information, see Volume Activation Management Tool (VAMT) Technical Reference.
• This also applies to updating Project Professional 2024 Preview to Project Professional 2024, or Visio Professional 2024 Preview to Visio LTSC Professional 2024.
• If you have the 32-bit version of Office LTSC 2024 Preview installed and want to install the 64-bit version of Office LTSC 2024, you must uninstall the preview first. This also applies if you're switching from 64-bit to 32-bit.
• If you're a volume licensed customer and want to install Office LTSC Standard 2024, you must first uninstall Office LTSC Professional Plus 2024 Preview.
