Prerequisites

• Office must be installed via Click-to-Run (the default since Office 2019). Ohook does NOT work on MSI installs.

• Administrator account on the local machine
• Antivirus paused for ~2 minutes (whitelist the download folder)

What Ohook does

Ohook patches a single Office Click-to-Run DLL (sppc.dll) so that Office reports as locally licensed. The patch is persistent — it survives Office monthly updates because the patcher reapplies after every Click-to-Run refresh.

Editions supported

• Microsoft 365 Apps for Business / Enterprise (Current channel)
• Microsoft 365 Personal / Family / Home
• Office 2024 — Home & Business, Pro, LTSC
• Office 2021 — Home & Business, Pro, LTSC
• Visio 2024 / 2021 LTSC
• Project 2024 / 2021 LTSC

Why Ohook beats Online KMS for Office 365

Online KMS leases Office for 180 days and requires re-activation every 7 days against a public KMS host. Ohook patches the DLL once and the install stays permanently activated, fully offline. No scheduled tasks, no services, no port 1688 traffic. This is exactly why Ohook is the recommended method for every Microsoft 365 install in 2026.

Verification commands

Open an elevated CMD and run:

• cd "C:\Program Files\Microsoft Office\Office16"
• cscript ospp.vbs /dstatus
• Look for: LICENSE STATUS: ---LICENSED--- and a far-future grace period
