How do I reinstall my Microsoft Volume Licensing Key

Diana Zeunen 0

Dell worked on my computer and reset my computer, so I lost all my programs. How do I reinstall my Microsoft Office Professional Plus 2019? I have my Microsoft Volume Licensing Key. I don't think this is Office 365 because it's not a subscription.

Dear @Diana Zeunen,
Welcome to Q&A Forum.

I understand that your computer was reset by Dell and, as a result, Microsoft Office was removed. You would like to reinstall Microsoft Office Professional Plus 2019, and you have a Volume Licensing key.

Office Professional Plus 2019 is a Volume License (one‑time purchase) product. This type of license is installed and activated differently from Microsoft 365 or retail Office versions. For Volume License editions, the product key alone is not used to download Office. The installation files are provided by the organization or administrator that owns the Volume Licensing agreement.

To reinstall Office Professional Plus 2019: Please contact the IT department, administrator, or organization that originally provided your Volume Licensing key and request the official Office Professional Plus 2019 Volume License installer (ISO or setup files). Then you can install Office using that installer and activate Office using the same Volume Licensing key (MAK), or through the organization’s activation system (KMS), as they instruct.

If the key was purchased from a third‑party seller If the Volume Licensing key did not come from an organization with a Microsoft Volume Licensing agreement, it may be an improperly resold key. In that case, activation may fail after reinstall, and Microsoft may not be able to support continued use of that key. Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.

I truly appreciate your patience and understanding. If you have any further questions or need further clarification, please feel free to reach out. I'm looking forward to hearing from you.

Thank you for your cooperation.

There is no IT Department and I am the administrator. I purchased it from Techsoup and have the volume licensing Key. It was on my computer before but was uninstalled when Dell reformatted my computer when they repaired it. Where can I find the download to install it again?

Thank you for more information.

Due to you are an only admin, you can follow below steps to troubleshoot and reinstall Office Professional Plus 2019 (Volume License) using the Microsoft 365 Admin Center.

First, please confirm that the admin account has Volume Licensing permissions. Being a Global Admin or a local administrator on the computer is not sufficient. The account must have a Volume Licensing role (for example, Volume Licensing Administrator or Product Downloads Manager) to view installers and product keys.

Next, sign in to the Microsoft 365 Admin Center at https://admin.microsoft.com and navigate to Billing > Your products > Volume licensing. Select Downloads & keys and check whether Office Professional Plus 2019 is listed. If it appears, the official installer (ISO or EXE) and the product key can be downloaded directly from this page.

If Office Professional Plus 2019 does not appear in the Volume licensing section, this indicates that the license is not associated with the current tenant or the signed‑in admin account. In this case, the admin will need to confirm which tenant or organization owns the Volume Licensing agreement, or contact the reseller or organization that originally provided the license.

After obtaining the installer, Office can be installed on the device and activated using the existing Volume License key (MAK or KMS), depending on how activation is configured in the organization.

I cannot login to the Microsoft 365 Admin Center because I no longer have access to the email.

Dear @Diana Zeunen,
Because the license was purchased from TechSoup, they can:

Verify your purchase

Help update or reassign the registered email

Guide you on how to regain access to the Volume Licensing portal

TechSoup is the only party that can assist if the license needs to be re‑associated at the reseller level.

Answer 2

Office Professional Plus 2019 with a Volume Licensing (VL) key is installed and activated differently from retail or Microsoft 365 subscriptions.

For Volume License editions such as Office Professional Plus 2019, installation media and activation are normally managed by the organization that owns the Volume Licensing agreement. The correct way to reinstall is:

Contact the organization’s IT department or Volume Licensing administrator that provided the Office Professional Plus 2019 key.
Request the official Office 2019 Volume License installation source (ISO/installer) and the appropriate activation method (MAK or KMS) for the Volume Licensing Key already held.
Use that official VL installer to install Office Professional Plus 2019, then activate it with the provided Volume Licensing Key or via the organization’s KMS infrastructure, as instructed by IT.

If the key was obtained from a third-party seller and not through an organization’s Volume Licensing agreement, it may be an improperly resold Volume License key and may not be eligible for continued activation. In that case, the recommendation is to obtain a legitimate retail or Microsoft 365 license instead.
