Overview
Office Professional Plus 2021 is the complete perpetual Office suite. This listing covers five devices from a single key — install on each machine in turn using the same 25-character key. This is a genuine retail license.
What’s included
Devices
5 — one key, five installations
Applications
Word, Excel, PowerPoint, Outlook, OneNote, Access, Publisher, and Skype for Business
A note on Teams
Microsoft’s own documentation is contradictory about whether the Teams client ships with Office LTSC 2021 — one page lists it, another says it was removed. Do not buy this expecting Teams; the free Teams client is a separate download either way
License type
Perpetual — one-time purchase, no subscription
Internet required
For activation only; the applications run offline afterwards
System requirements
Processor: 1.1 GHz or faster, 2-core
Memory: 4 GB RAM
Disk space: 4 GB of available space
Display: 1280 x 768 screen resolution
Graphics: hardware acceleration requires DirectX 9 or later
Operating system: Windows 11, Windows 11 LTSC 2024, Windows 10 LTSC 2021 or 2019, or Windows Server 2025, 2022 or 2019

Download instructions
Open the email from Vaneyo containing your license key — it arrives within minutes of purchase. Check your spam folder if it is not in the inbox.
Go to Microsoft’s setup page at office.com/setup and sign in with the Microsoft account the license should belong to. Create one first if you do not have an account.
Enter your 25-character product key. The license is redeemed to your account and the download becomes available.
Choose Install and let the installer download.
If you would rather we walk you through this, that is covered by your Installation Warranty — just reply to your order email.
Installation and activation
Uninstall any existing version first. Running two Office-family releases side by side on one PC causes activation errors and file-association problems.
Run the installer and let it finish.
Open one of the applications from the Start menu.
Accept the Microsoft license terms when they appear.
Activation completes automatically if the key was redeemed to your account. If you are asked to sign in, use that same account.
Confirm it worked: go to File → Account and check that Product Information reports the product as activated.
If anything stalls, contact us — installation support is included with every order.
Compatibility
Operating systems: Windows 11, Windows 11 LTSC 2024, Windows 10 LTSC 2021 and 2019, and Windows Server 2025, 2022 and 2019.
File formats: reads and writes .docx, .xlsx and .pptx and opens the older .doc, .xls and .ppt formats, so files move both ways with Office 2016, 2019, 2024 and Microsoft 365.
Mail: Outlook connects to Exchange, Microsoft 365 mailboxes, IMAP and POP accounts.
Cloud: saves to OneDrive and SharePoint.
Not compatible with: macOS, Linux, ChromeOS, iPad and Android — the Mac and mobile versions are separate products. Access and Publisher are Windows-only in any case.
How it compares
Professional Plus 2021 vs Home & Business 2021 — Home & Business covers Word, Excel, PowerPoint and Outlook. Professional Plus adds Access and Publisher.
Office 2021 vs Office 2024 — the decisive difference today is support: 2021 ends October 13, 2026, 2024 runs to October 9, 2029.
Office 2021 adds Excel’s dynamic-array functions including XLOOKUP, and newer presentation and collaboration tools.
Office 2021 vs Microsoft 365 — Office 2021 is bought once and never changes. Microsoft 365 is billed monthly or yearly, covers several devices, includes cloud storage and keeps gaining features.
5 PC vs single PC — if you are equipping three or more machines, the five-device key is the cheaper route. Each of the five activations is tied to the machine it is used on, so plan the five before you start.
5 PC vs the bind license — the five-device key covers more machines; the bind license covers one machine but lets you move it whenever you like. If your problem is number of computers, buy this. If your problem is changing computers, buy the bind license.
An email containing your 25-character product key, the official Microsoft download link and step-by-step activation instructions. Nothing is shipped — it is a digital licence.
How quickly will my key arrive?
Within minutes of your payment clearing, by email. If it is not in your inbox, check your spam or junk folder. If you still cannot find it, contact us and we will resend it straight away.
Is this a genuine Microsoft licence?
Yes. This is a genuine Microsoft product key with full activation support. Vaneyo is an authorized reseller and holds a Microsoft partnership certificate.
Is this a subscription or a one-time payment?
A one-time payment. There are no renewals and no recurring charges. The key stays valid and Office keeps working for as long as the product is not uninstalled or deactivated.
How many computers can I use this key on?
Five. It is a single key valid for five separate devices.
Can I install it on the five PCs at different times?
Yes. There is no deadline — use the activations as and when you need them.
Can I move the licence to another computer later?
This is a retail key tied to the machine it activates, so a hardware change means a new key is needed. If you expect to change computers often, ask us about our bind licence products, which move with you.
Where do I download the software?
From Microsoft directly. Your email includes the official download link, so you always install from the genuine source.
Do I need an internet connection?
Only to download the software and activate the key. After that Office runs offline.
Will it work in my country and language?
Yes. The key is valid in all regions and all languages — choose your language during installation.
What if activation does not work?
Contact us and we will fix it. Our Installation Warranty means we guarantee the installation will work correctly, and our team will stay with it until it does.
Can you help me install it?
Yes, at no extra cost. Reply to your order email and our multilingual team will walk you through installation and activation, or complete it with you.
Is this really one key for five computers?
Yes. One 25-character key, used to activate five separate devices. It is not five keys.
Do all five have to be installed at the same time?
No. You can install them as you go. Each activation is tied to the machine it is used on, though, so a computer you later replace does not free up its activation.
Which applications are included?
Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher, plus Skype for Business.
Does it include Microsoft Teams?
Treat the answer as no. Microsoft’s own documentation contradicts itself on whether the Teams client ships with Office LTSC 2021. The free Teams client is a separate download in any case, so nothing is lost.
Does Office 2021 run on Windows 10?
On the LTSC releases of Windows 10 — LTSC 2021 and LTSC 2019 — yes. Microsoft lists Windows 11, Windows 11 LTSC 2024, Windows 10 LTSC 2021 and 2019, and Windows Server 2025, 2022 and 2019.
Do I need to stay online to use Office?
No. An internet connection is needed to redeem the key and activate; after that the applications run offline.
Much better than paying for a monthly subscription.
No problems so far, everything works as expected.
Activated successfully on multiple computers.
Good value for a one-time purchase license.
All Office apps are included and working well.
