This guide is for Microsoft Project Professional 2024 LTSC on Windows. Project is a standalone product that installs alongside Office, and the version and bit rules below decide whether it installs cleanly.
Before you start
- Requires Windows 10 or Windows 11, 4 GB RAM and 4 GB free disk space.
- Check any Office already on the PC. Project 2024 should sit alongside Office 2024 or Microsoft 365, in the same bit version. To check, open Word and go to File > Account > About Word; the top line says 32-bit or 64-bit. If Office 2021 or 2019 is installed, upgrade it first or expect errors.
- Have your 25-character key from the delivery email ready.
Step 1: Remove any older Project
If Project 2021, 2019 or an evaluation is installed, uninstall it under Settings > Apps > Installed apps and restart. Leave Office in place if it is 2024 or Microsoft 365.
Step 2: Download the Project 2024 installer
Use the download link in your delivery email. It points to the official Microsoft installer for Project Professional 2024. Pick the bit version that matches your Office, or 64-bit if the PC has no Office.
Step 3: Install
- Close all Office apps.
- Run the installer and accept the User Account Control prompt.
- Keep the PC online until you see You're all set.
Step 4: Activate Project 2024
- Open Project from the Start menu.
- Choose Enter a product key instead, or go to File > Account > Change product key.
- Enter your key and follow the prompts. Sign in with your own Microsoft account if asked.
- Confirm File > Account shows Product Activated: Microsoft Project Professional 2024.
If your delivery email states your key uses phone activation, select I want to activate the software by telephone in the wizard.
Project 2024 specific problems
Error 30182 or "We found a problem" during install
The existing Office is a different generation or bit version. Either upgrade Office to 2024 in the matching bit version, or install Project in the same bit version as the existing Office.
Word or Excel break after installing Project
Same cause. Uninstall Project, repair Office (Settings > Apps > Microsoft Office > Modify > Online Repair), then reinstall Project in the matching version.
"Invalid product key"
Check the installed product is Project Professional 2024, not Standard, and not Visio. A Visio 2024 key is a different product.
