Related: Roblox Game Codes Remember to use Roblox script executors responsibly, as many of the scripts can give players incredibly unfair advantages in user-made games.

Some other executors include: krnl, Fluxus, Script-Ware, Script-Ware M, and Synapse. Once the download is complete, install the Roblox Executor and open and log into it using your Roblox account.

If KRNL-Injector failed to find the Roblox process, delete KRNL App data and see. If that doesn't help follow the solutions mentioned in this post to resolve the issue.
