Frequently Asked Questions
Is this a subscription or a one-time purchase?
Project Professional 2021 is a one-time purchase (perpetual licence). You pay once and use it indefinitely — no recurring fees.
Can I install Project 2021 on more than one PC?
No. Each Licendi licence activates one Windows PC. For multi-device use, purchase additional licences.
Can I transfer the licence to a new computer?
No. Both OEM and Retail variants bind the licence to the first activated device. Retail supports reinstalls on the same PC; OEM does not.
Does Project 2021 work on macOS?
No. Microsoft has never released Project for Mac. For Mac-based project management, consider Microsoft 365 web apps with Planner, or a third-party tool like OmniPlan or Merlin.
