Activating Volume License Project and Visio Click to Run installations


You are unable to install Project or Visio Volume License editions along side normal Office 2013/2016 click to run installations. You may get an error like "this product key is for the volume-licensed version of project 2016"


Microsoft keep moving the goal posts! 

  1. Use the Office 365 Offline Deployment tool to download the "ProjectStdXVolume" product.
  2. Before running the setup, amend the config file to include the PID key Like so:

<Product ID="VisioProXVolume" PIDKEY="69WXN-MBYV6-22PQG-3WGHK-RM6XC">

Choose te correct PID for the required edition:

Visio Standard 2016  VisioStdXVolume  NY48V-PPYYH-3F4PX-XJRKJ-W4423 
Visio Professional 2016  VisioProXVolume  69WXN-MBYV6-22PQG-3WGHK-RM6XC 
Project Standard 2016  ProjectStdXVolume  D8NRQ-JTYM3-7J2DX-646CT-6836M 
Project Professional 2016  ProjectProXVolume  WGT24-HCNMF-FQ7XH-6M8K7-DRTW9 
Next, to activate the software make sure you have the C2R-P MAK key, not the MSI MAK key.

MAK keys that you use for Windows Installer (MSI) installations of Visio and Project won't work with the Office Deployment Tool. You need a different MAK key to deploy volume licensed editions of Visio and Project with the Office Deployment Tool. To get that MAK key, log into the Volume Licensing Service Center (VLSC) and use the key listed under "C2R-P for use with the Office Deployment Tool."
