How to Install Roblox Executors — Complete Setup Guide (2026)
New to Roblox scripting and don't know how to set up an executor? This step-by-step guide covers how to install every major Roblox executor in 2026 — on both PC and mobile.
Before You Start
Disable antivirus — Windows Defender and other AV software will flag executors. This is a false positive, but you need to whitelist or disable AV temporarily
Use a VPN — Optional but recommended for extra privacy
Create an alt account — Never use scripts on your main account
Installing Delta Executor (PC)
Go to the official Delta website (link on our site)
Download the latest version
Extract the ZIP file to a folder
Add the folder to your antivirus exclusions
Run Delta.exe as administrator
Open Roblox and join a game
Click "Inject" in Delta
Wait for the "Injected" confirmation
Paste your script and click Execute
Installing Delta Executor (Mobile)
Download the Delta APK from the official site
Enable "Install from unknown sources" in your Android settings
Install the APK
Open Delta and grant the required permissions
Open Roblox through Delta's built-in browser
Join a game — the executor will auto-inject
Paste and execute your scripts
Installing Synapse X (PC)
Purchase a license from the official Synapse X website ($20)
Download the installer after purchase
Run the installer as administrator
Add the installation folder to antivirus exclusions
Open Synapse X
Open Roblox and join a game
Click "Attach" in Synapse X
The script editor will open — paste your script and press Execute
Installing KRNL (PC)
Download KRNL from the official site
Extract the ZIP file
Add the folder to antivirus exclusions
Run KRNL.exe as administrator
Complete the key system (follow the link, wait, get key)
Paste the key when prompted
Open Roblox and join a game
Click Inject, then paste and execute your script
Installing Fluxus (PC)
Download Fluxus from the official site
Extract and add to antivirus exclusions
Run Fluxus.exe as administrator
Complete the key system
Open Roblox, join a game, and click Inject
Paste your script and execute
Common Installation Problems
Antivirus deletes the file
Add the executor folder to Windows Defender's exclusion list: Settings → Virus & Threat Protection → Manage Settings → Exclusions → Add folder.
"Injection failed" error
Make sure Roblox is running before you click Inject. Also try running the executor as administrator.
Key system not working
Use a different browser, disable ad blockers, and make sure you complete all steps (wait timers, captchas, etc.).
Executor won't open
Install the required C++ redistributables and .NET Framework. Most executors need these to run.
Mobile-Specific Notes
Only Android is supported (iOS requires jailbreak)
Some executors require you to uninstall the official Roblox app first
Always download from official sources — fake APKs contain malware
Mobile executors are generally less stable than PC versions
Post-Installation Checklist
Test with a simple script (like a walk speed change) to confirm it works
Keep your executor updated — Roblox updates can break older versions
Bookmark the official download page for quick access to updates
Never share your executor license key or key system bypass
