On 64‑bit Linux systems, the kernel may use different system call numbers for getuid and geteuid compared to 32‑bit mode, but these details are fully abstracted by the C library. If you are writing assembly or working directly with system calls (rare in application development), you must be aware of the underlying ABI. For typical C, C++, Rust, Go, and Python code, calling geteuid() or the language wrapper is all that is needed.

: In PowerShell, execution policies might block the script from launching the binary. Run Set-ExecutionPolicy Bypass -Scope Process before running the command. What is getuidx64

: In enterprise environments, network administrators often use AppLocker or Software Restriction Policies to block unapproved 64-bit binaries from executing out of the C:\Users\ directory. Move the tool to C:\Program Files\ or a dedicated tools folder.
