Fusion 360 Portable Download Install Info
A: Yes, you can store the official installer on your USB drive. But you still need to run it on each new computer, which writes registry entries and program files to the local hard drive. That is not “portable” in the traditional sense, but it is fast (the installer is small, then it downloads the latest version).
Download the official installer from Autodesk Fusion 360. Run the installer. It will place the main program in:
C:\Users\[YourName]\AppData\Local\Autodesk\webdeploy\production\
Note: Do not try to move this folder directly.
While a true portable version doesn’t exist, you can achieve a semi-portable workflow that lets you use Fusion 360 on multiple computers without reinstalling from scratch each time. This method uses a USB drive for settings and cache redirection, plus the standard online installer.
