You cannot create a "plug-and-play" portable executable ( .exe ) for Fusion 360 in the same way you can for Notepad++ or 7-Zip.

Portable versions are often used to bypass licensing, which Autodesk mitigates through frequent online "heartbeat" checks. You cannot create a "plug-and-play" portable executable (
Why Fusion 360 isn’t offered as a portable app Attempting to repackage this into a portable structure
The technical barriers to creating a portable Fusion 360 install are substantial and effectively insurmountable for a standard user. Autodesk, like many modern software vendors, has deliberately shifted to a managed deployment model. Fusion 360 installs using a web-based service that places files in privileged system directories (e.g., Program Files\Autodesk\webdeploy ) and the user’s profile directory. It also writes dozens of registry keys, installs background services for auto-updates, and integrates with the Windows Credential Manager for single sign-on authentication. Attempting to repackage this into a portable structure would require reverse-engineering these dependencies, spoofing file system calls, and maintaining a writable sandbox—a task approaching the complexity of a full operating system emulation. Moreover, the licensing mechanism is a constant online validation handshake. A portable drive moved between machines with different hardware IDs would trigger repeated license re-activations, quickly exhausting the (free) personal use or trial limits and flagging the account as suspicious. The very act of seeking a "portable cracked" version—frequently the hidden implication of such search terms—would require patching out this network license check, rendering the software legally and functionally obsolete from the moment of modification.
Autodesk uses a sophisticated licensing system (FlexNet or Named User). This system writes machine-specific identifiers to the registry and hidden folders (e.g., C:\ProgramData\FLEXnet ). If you try to run Fusion 360 from a USB drive on a different computer, the licensing server sees a "new device" and often requires re-activation—which can consume one of your device slots.
