Why? Because Acronis is a application.
Why, then, has Acronis never released a true portable version for Windows? Several technical and business reasons apply. From a technical standpoint, backup software requires deep integration with the operating system's Volume Shadow Copy Service (VSS), low-level disk drivers, and filter drivers to capture a consistent snapshot. Installing these drivers requires administrative privileges and often a system reboot. A portable executable running from a USB drive cannot install kernel-mode drivers on the fly without triggering security warnings, compatibility issues, or leaving residual driver files. Moreover, licensing and activation are central to Acronis’s business model. Acronis is a commercial product tied to subscriptions or perpetual licenses per machine. A truly portable version—copyable to any PC and run without installation—would be impossible to enforce license limits. Users could theoretically run it on unlimited computers, bypassing the need to purchase multiple licenses. Consequently, Acronis (like competitors such as Macrium Reflect and EaseUS Todo Backup) has deliberately avoided portable versions. acronis portable version

Instead of just being a static recovery tool, this feature would allow the portable Acronis USB to "inject" its backup and security capabilities into any host computer's running OS without installation.
Instead, create bootable media:
