Install Office 2021 Before Project 2024
According to official documentation, both applications can coexist on the same PC if installed in the correct order, which is installing the older version first.
Microsoft generally supports running different versions of its Office suite and standalone products on the same machine, provided they use compatible installation technologies like Click-to-Run. The standard best practice is to install the older version of the software first. This prevents newer shared system files and registry keys from being overwritten by older ones.
Run the Microsoft Office 2021 installer and follow the on-screen prompts to complete the setup process. Once finished, activate the software using your license key.
Open an Office 2021 application such as Word or Excel to ensure it runs correctly and check for any available updates.
Run the Microsoft Project 2024 installer. The setup wizard will detect the existing Office components and configure Project 2024 to properly coexist with your Office 2021 installation.
