Even with the "top" methods, issues appear.

Problem: "Unity is already running" error on a new PC. Fix: Delete U:\Unity\Cache\Lock file and U:\Projects\MyGame\Library\ArtifactDB. Unity locks artifacts by machine ID. unity portable install top

Problem: Android SDK or IL2CPP missing. Fix: You must install Android Build Support, NDK, and JDK directly on the portable drive. In Hub -> Preferences -> External Tools, point Android SDK to U:\Unity\AndroidSDK. Even with the "top" methods, issues appear

Problem: The PC asks for Admin rights to run Unity. Fix: You didn't use the symlink method correctly. If you try to install Unity directly to Program Files on the external drive, it demands admin. Keep Unity in a root folder like U:\Unity. Unity locks artifacts by machine ID
