⚠️ Important
Uninstall any previous version of Office (2010, 2013, 2016) before installing Office Professional Plus. Two versions cannot coexist.
Step 1: Download Office Professional Plus
Official Microsoft Method (Recommended)
To download the official Office Professional Plus ISO, Microsoft provides the Office Deployment Tool (ODT). This is the safest and most reliable method.
- Go to microsoft.com/download/details.aspx?id=49117
- Download
officedeploymenttool.exe(~3 MB) - Run the executable and extract files to
C:\ODT - Open Notepad as administrator
- Create a
configuration.xmlfile with this content:
<Configuration>
<Add OfficeClientEdition="64" Channel="PerpetualVL2021">
<Product ID="ProPlus2021Volume" PIDKEY="YOUR-25-CHARACTER-KEY">
<Language ID="en-us" />
<ExcludeApp ID="Groove" />
<ExcludeApp ID="OneDrive" />
</Product>
</Add>
<Display Level="Full" AcceptEULA="TRUE" />
</Configuration>
Replace PIDKEY with your product key, then:
- Save the file in
C:\ODT\configuration.xml - Open PowerShell as administrator
- Execute:
cd C:\ODT - Launch installation:
.\setup.exe /configure configuration.xml
The download starts automatically (~2 GB). Installation follows immediately. Total duration: 15-30 minutes depending on your connection.
Step 2: Install Office Professional Plus
Standard Installation Procedure
If you use ODT, installation is automatic after the setup.exe /configure command. If you use OfficeSetup.exe:
- Launch: Double-click on OfficeSetup.exe
- UAC: Accept the User Account Control prompt
- Download: The installer downloads files (progress bar)
- Installation: Applications install automatically (5-10 min)
- Completion: Message "You're all set"
💡 Tip
During installation, don't turn off your PC and keep the internet connection active. Interruption could corrupt the installation.
Step 3: Activate Your Office License
Manual Activation
If automatic activation fails or you haven't used ODT:
- Open Word
- Click File → Account
- Click "Change Product Key"
- Enter your 25-character key
- Click "Install"
- Wait for connection to Microsoft servers (5-30 seconds)
- Confirmation "Office is activated"
Troubleshooting Activation Issues
Error 0xC004F074
Cause: KMS server not found (MAK/Retail key required).
Solution:
- Open PowerShell as administrator
- Execute:
cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /dstatus - If you see "VOLUME_KMSCLIENT", your key is KMS (incompatible with internet activation)
- Contact our support for a Retail key
Error 0x8007000D
Cause: Corrupted installation files.
Solution:

If your key consistently refuses activation, it may be fraudulent. Only purchase from official Microsoft resellers like AllKeyMasters.
