This guide explains how to download, install and activate Microsoft Project Professional 2024 on a Windows 10 or Windows 11 PC.
The installation is straightforward and normally takes around 10 to 30 minutes depending on your computer and internet connection.
Before You Install Microsoft Project Professional 2024
You will need:
- A reliable broadband connection to download and activate Microsoft Project.
- A genuine 25-character Microsoft Project Professional 2024 product key.
- A compatible Windows 10 or Windows 11 computer.
- Administrator permission on the PC to install software.
Already have Microsoft Office installed? Project and Office installed on the same computer normally need to use compatible installation technology and matching 32-bit or 64-bit architecture. If setup reports an Office compatibility error, do not immediately uninstall your existing working Office installation.
Step 1: Download Microsoft Project Professional 2024
