Transfer and Reinstall Microsoft Project Professional 2019

Follow these steps to safely move your Microsoft Project license from your old Mac to your new Windows 11 ARM environment in Parallels.

Microsoft Project licenses typically permit installation on only one device at a time. To avoid activation errors on your new MacBook, it is essential to uninstall the software from the previous computer while connected to the internet. Windows 11 on ARM includes a built-in emulator that allows standard Windows x86 applications to run.

1
Uninstall from the old Mac

Start Windows 10 on your older Intel-based Mac. Navigate to Settings > Apps > Apps & features. Locate 'Microsoft Project Professional 2019' in the list, click it, and select 'Uninstall'. This step helps free up your license activation slot.

2
Download the installer on the new Mac

On your new MacBook, launch Windows 11 Pro for ARM through Parallels. Open a web browser, go to account.microsoft.com/services, and sign in with the Microsoft account associated with your Project 2019 purchase. Locate your Project license and click 'Download'.

3
Install and run the software

Run the downloaded setup file and follow the on-screen instructions to install Project Professional 2019. Once the installation is complete, launch the application from the Windows Start menu.

Activate the new installation

When prompted upon launching, sign in with your Microsoft account or enter your original 25-character product key. Follow the prompts to complete the online activation process.
