Microsoft project management software used to plan, manage, and communicate a project schedule and other information among workgroup members, project managers, and other stakeholders.
Dear @Darren,
Welcome to Q&A forum. I understand you’d like to reinstall Microsoft Project 2019 on a new computer, but you no longer have access to the old device or the email account originally used. You do still have the product key and purchase details.
Please note that Project 2019 is a one‑time purchase license that is linked to the Microsoft account used during the first setup. Because the original account and device are no longer accessible, the product key alone may not be enough to reinstall or activate the software on a new computer.
Since you have proof of purchase, the best next step is to contact Microsoft Support so they can verify ownership and help recover or reactivate the license for use on your new device.
Go to Contact - Microsoft Support
Choose Microsoft 365 > Click get Home Support
Search for "Account" > Get Help > Contact Support
Choose a relevant option
For product/service, select "Other Products."
For category, choose "Billing and Account"
Look for and select "Chat with a support agent in your web browser" or a similar callback option
Explain your situation clearly, reference the error message you get.
Please note: The Chat support team only works at certain times, so if the last window says you are not available, try to open it again the next day. If you prefer phone support, you can leave a phone number. That way, they can contact you back and help you further.
Note: Please understand that as a forum moderator, my role is to provide general guidance and troubleshooting support. I don’t have access to internal systems or backend tools, and I appreciate your understanding of these limits.
I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work.
The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.
Thank you for your patience and understanding. I'm looking forward for your reply.
