Downloading "portable" cracks is the #1 way project managers get hit with ransomware. These files often contain keyloggers designed to steal your login credentials for corporate networks.

Unlike a desktop app on a USB drive, web-based projects allow multiple team members to update tasks simultaneously.

If you are a power user needing EVA (Earned Value Analysis) or multiple undo levels, you must use Microsoft Project—portable or not. If you just need basic Gantt charts, switch to ProjectLibre Portable . It runs perfectly from a USB stick, requires no registry changes, and opens ancient MPP files (pre-2013).
