Use the Hub to install your preferred Unity Editor version (e.g., 2022.3 LTS).
Creating a "portable" Unity installation—one you can run directly from a USB drive or external SSD across different computers—is possible, though it requires specific steps since Unity Hub is typically tied to your system drive. Top Ways to Create a Portable Unity Install
The standard installation of the Unity Editor via the Unity Hub involves deep integration with the host operating system, including registry modifications, system cache utilization, and fixed default directory paths. While suitable for single-user development stations, this model presents significant challenges for educational laboratories, build servers, and developers managing multiple engine versions. This paper explores the methodology of creating a "portable" Unity installation—a self-contained deployment that runs independently of system registries and fixed paths. It details the technical execution of such an installation, the management of licensing and package caches, and the comparative advantages regarding system hygiene and version control. unity portable install top
Because Windows assigns dynamic drive letters to external devices, hardcoded file paths inside shortcuts will fail across different host computers. You can solve this by writing a custom startup script ( launch.bat ) to intercept and override default system registry paths. Place this script directly inside the root folder of your portable drive:

: For users with limited internal drive space, moving the multi-gigabyte Unity Editor and its modules to a high-capacity pendrive (e.g., 64GB or larger) is a common workaround. Unity Discussions Top Ways to Create a Portable Environment
Lock down an exact Unity version and build environment across different physical machines. Use the Hub to install your preferred Unity
For game developers, the ability to work on projects anytime, anywhere is invaluable. The official Unity Hub makes managing multiple Editor versions easy, but it's not designed for portability. Whether you're moving between computers, building a mobile workstation on a USB drive, or setting up classroom lab stations, a truly portable Unity installation gives you unprecedented freedom and efficiency. This comprehensive guide explores the top methods to create a portable Unity environment, from lightweight Editor alternatives to complete USB-driven setups, so you can develop on the go without missing a beat.
A dedicated Unity.exe in the root of the USB drive (copied from C:\Program Files\Unity\Editor ) that initializes without relying on Windows registry keys. Because Windows assigns dynamic drive letters to external
