How to Activate Microsoft Office — Every Version, Every App
One licence store covers the whole Office suite, so a single activation run licenses Word, Excel, PowerPoint, Outlook, Access, Publisher, OneNote, Project and Visio at once. Pick your install type below, then follow the app-specific guide if you need step-by-step screenshots.
Identify your Office install type first
- Open any Office app → File → Account. 'Microsoft 365 Apps' or a version number with an update channel means Click-to-Run → use Ohook.
- No update channel listed and an install path under Program Files\Microsoft Office\Office16 usually means MSI → use KMS.
- Retail Click-to-Run can be converted to Volume first if you specifically want the KMS path.
- LTSC builds are always safe with Ohook — no channel updates to revert the licence.
Ohook — permanent, offline (recommended)
- Works with Office 2019, 2021, 2024, LTSC and Microsoft 365 Apps.
- No expiry date, no KMS host, no internet connection required.
- Survives monthly Click-to-Run updates.
- Steps: close all Office apps → run the activator as administrator → Office tab → Ohook → wait for the success message.
KMS — 180-day renewing lease
- Intended for Volume-License MSI builds such as Office 2013 and Office 2016.
- Installs a scheduled task that renews the lease automatically.
- Verify with: cscript ospp.vbs /dstatus in the Office install folder.
- Switch to Ohook if you see error 0xC004F074 (no KMS host reachable).
Verify the whole suite
- Each app: File → Account → Product Information → 'Product Activated'.
- No yellow or red activation banner in Word, Excel or PowerPoint.
- Saving, printing and add-ins all work again.
- Command line: cscript ospp.vbs /dstatus → LICENSE STATUS: ---LICENSED---.
Most common Office activation errors
- 0xC004F074 — no KMS host reachable → use Ohook.
- 0xC004C008 — activation count exceeded on the host → use Ohook.
- 0x8007232B — DNS name does not exist → set the KMS host manually or switch method.
- 'Unlicensed Product' after update → restart the app, then re-run the activator once.
- Mixed installs (365 + perpetual) → uninstall one before activating.
Frequently asked questions
▸How do I activate Microsoft Office for free?
Run the activator as administrator, open the Office tab and choose Ohook for Click-to-Run installs (Office 2019, 2021, 2024, LTSC and Microsoft 365 Apps) or Online KMS for Volume MSI installs (Office 2013/2016). Activation takes a few seconds and needs no product key.
▸Which Office versions are supported?
Office 2010, 2013, 2016, 2019, 2021, 2024, Office LTSC 2021/2024 and Microsoft 365 Apps, on Windows 7 through Windows 11 25H2, in 32-bit and 64-bit.
▸Does one run activate Word, Excel, PowerPoint and Outlook together?
Yes. Click-to-Run Office keeps a single licence store, so every installed app — Word, Excel, PowerPoint, Outlook, Access, Publisher, OneNote, Project and Visio — is licensed in the same pass.
▸What is the difference between Ohook and KMS for Office?
Ohook writes a permanent local licence with no expiry and no network use. KMS installs a 180-day lease that renews against a KMS host. Ohook is the better choice whenever the install is Click-to-Run.
▸Is Office activation permanent?
Ohook activation does not expire and survives monthly updates. Only a full Office reinstall or an OS reinstall requires running it again.
▸Will Office still receive security updates?
Yes. Update channels keep working exactly as before, and the licence persists across them.
▸Why does Office say 'Unlicensed Product' after activation?
Almost always a second Office install or a cached token. Uninstall older Office versions, restart the app, and re-run the activator once.
▸Does this work on Office for Mac?
No. These methods target Windows builds of Office only.
