Questions, answered.
Downloads, attach, scripts and updates. If your question is not here, the guide covers the full setup with screenshots of each step.
What is Delta Executor for PC?
Delta Executor is a Luau script executor for Roblox. The PC build runs natively on Windows, attaches to the Roblox client and executes .lua scripts inside the game without an emulator or a second device.
Is Delta Executor free?
Yes. The desktop build is free to download and includes the full execution engine, the built-in script hub and the editor. There is no paid tier and no key system.
Do I need an Android emulator?
No. Earlier Delta releases were Android-only. This build is a native Windows application, so it does not use an emulator, a phone or a second device.
Which Windows versions are supported?
Windows 10 and Windows 11, 64-bit. Delta needs the official Roblox client installed and roughly 60 MB of free disk space.
Which Roblox versions does it work with?
Delta attaches to the current public Roblox client. The attach layer is updated after each Roblox release, usually within a day, and the app checks for a compatible build whenever it starts.
How do I run a script?
Open Roblox, launch Delta, press Attach, paste a script into the editor or load a file, then press Execute. Output and errors appear in the console panel below the editor.
Where do scripts come from?
The built-in hub includes more than 5,400 community scripts sorted by category. You can also load any .lua or .txt file from your computer, or write your own in the editor.
Does Delta support multiple Roblox windows?
Yes. When more than one Roblox client is open, Delta lists each process and lets you choose which one to attach to. Each instance keeps its own script state.
How often is Delta updated?
The app checks for updates on launch. Attach compatibility fixes ship within a day of a Roblox update, and the script hub refreshes continuously.
