Hi @Justin Irvine
Regarding your issue, the "exceeded license" message typically appears when the product key is re-entered on a new PC. That's because a retail Project 2021 key can only be redeemed once; after that first redemption, the entitlement is linked to the Microsoft account it was redeemed under, not to the key itself. Re-typing the key on the new laptop causes the system to treat it as an already-redeemed key, which triggers the error.
To transfer Project 2021 to your new PC, here are some steps you can try:
- On you new device go to https://m365.cloud.microsoft/apps. If you're not already signed in, select Sign in with the same account used when you first activated Project.
- From the Microsoft 365 home page select Install and more.
- If you're not sure which Microsoft account the key was originally redeemed to, you can check at account.microsoft.com/services Project 2021 should appear in the list of products tied to that account.
For more information, refer to: Install Project
If it was redeemed before, the key is already attached to your account.

When you open Project, it will prompt for activation please sign in (if account-linked) or enter your product key.
For reference: Activate Office for Windows
Note: For users in the European Economic Area (EEA), you can transfer your license to another person as permitted by applicable law, by contacting customer support. You’ll be required to verify your identity through your Microsoft account to confirm you have legitimate license rights. You’ll also need to provide an email for the person you’re transferring the license to. Upon verification, Microsoft will cancel your entitlement and will email the new licensee instructions for how to associate the license with their Microsoft account. (If the new licensee doesn’t already have a Microsoft account, they’ll need to create one.)
Hopefully this will help you get activated on the new laptop and if you continue to see the "exceeded license" error after signing in, feel free to share a screenshot of the exact message is possible.
