Guide

Short notes on installing Crescent, running scripts, managing accounts, and using the key system.

Getting started

Download the Windows build, install it, then open Crescent. You will need a free key before inject works on a new device.

  • Use Download for Windows from the home page or the menu.
  • Accept the User Terms when prompted.
  • Get a key, paste it in Crescent, then attach to Roblox.

Install & setup

Crescent currently ships a Windows build only. After download, run the installer and open the app from the Start menu or desktop shortcut.

  • If Windows SmartScreen appears, choose More info → Run anyway when you trust the file from this site.
  • Close other injectors before opening Crescent to avoid conflicts.
  • Keep Crescent updated so attach stays compatible with the latest Roblox client.

Inject & run

Open a script tab, paste or load your code, start Roblox, then press Attach / Execute. Inject is designed to finish in under a second on typical setups.

  • Use the editor for highlight and a quick output log.
  • If attach fails, restart Roblox and try again after the game has fully loaded.

Script editor

The built-in editor is made for quick edits: syntax highlight, tabs, and an output log so you can iterate without switching tools.

  • Paste a script or open one from Script Hub into a tab.
  • Run from the editor after attach succeeds; check the log if nothing happens.

Using Script Hub

Browse trending and verified scripts inside the app. Search by name or game, open a result, then run it without leaving Crescent.

Account manager

Save multiple Roblox accounts, launch the client, or join a place with Place ID and Job ID. Useful when you switch accounts often.

Key system

Keys are free. Choose a path (for example work.ink or LootLabs), finish the checkpoints, then copy the key back into Crescent. Duration depends on the path; the key locks to the device on first use.

Troubleshooting

Most issues come from an outdated build, a missing key, or attaching before Roblox has fully loaded.

  • Download the latest Crescent and reinstall over the old version.
  • Confirm a valid key is entered and not expired.
  • Fully close Roblox, reopen the game, wait until you are in-world, then Attach again.
  • If Windows blocks the app, use More info → Run anyway only for downloads from this official site.

Safety notes

Crescent is a third-party tool. Using it can violate Roblox rules and may risk account action. Only run scripts you trust.

  • Never share your key or account credentials with others.
  • Avoid scripts that ask for passwords, cookies, or wallet access.
  • Read the User Terms before downloading or using Crescent.

FAQ

Inject not working? Update Crescent, close other injectors, and make sure Roblox is fully in-game before Attach.

Key expired? Open Get Key again and complete a path for a new key. Permanent keys stay valid until revoked by the service.
