What Hyperion (Byfron) 64-Bit Anti-Tamper means in Bloxstrap

Roblox's 64-bit Windows security software that blocks DLL injection and process memory editing.

Because Bloxstrap never injects DLLs or modifies running memory — it only updates files on disk and launches the official signed Roblox executable — it is completely compatible with Hyperion.

Where you encounter this in the app

Bloxstrap wraps low-level Roblox configuration files, log watchers, and registry handlers into a clean WPF settings menu so you rarely need to edit raw files by hand.
