Installing Delta Executor takes under five minutes on every supported platform — but the exact steps differ between Windows, Android, and iOS. This guide walks you through each one, with screenshots worth of detail and every common hiccup (Defender false positive, Unknown Sources toggle, AltStore signing) covered so you don't get stuck.
Before we start, the single most important rule: only download Delta from the official site, deltaexecutor.website. Every other link floating around the internet — YouTube descriptions, Discord DMs, TikTok bios, random APK hosts — is either an outdated build, a tampered copy with malware, or a survey scam that wants your phone number. The official site is the only safe source.
Part 1 — Download Delta Executor on Windows (PC)
The Windows build is the easiest to install because it doesn't require a key. Total install time is about 90 seconds.
Step 1: Download the .exe
Click the "Download for Windows" button on the homepage. The file is about 24 MB and downloads in under 5 seconds on a typical broadband connection. The filename is Delta-Setup-v2.738.exe.
Step 2: Add the Folder to Windows Defender Exclusions
This is the step most people skip and then complain about. Windows Defender flags any program that allocates kernel memory — including Delta's signed driver — as a "trojan" or "hacktool". It's a known false positive, but Defender will silently quarantine the .exe if you don't whitelist the folder first.
Open Start → Settings → Privacy & Security → Windows Security → Virus & Threat Protection → Threat Protection Settings → Manage Settings → Exclusions → Add or Remove Exclusions. Click "Add an exclusion" → "Folder" and pick the folder where you'll save the Delta installer (we recommend C:\DeltaExecutor\). Click OK. Now Defender will ignore everything in that folder.
Step 3: Run the Installer
Double-click Delta-Setup-v2.738.exe. Windows may show a SmartScreen prompt — click "More info" → "Run anyway". Follow the 30-second setup wizard: accept the license, pick the install location (default is fine), and let the driver install.
Step 4: Launch Delta
Double-click the Delta icon on your desktop. The editor opens immediately — no key needed on PC. Leave Delta running in the background.
Step 5: Open Roblox and Inject
Open Roblox, join any game (try your own private server first if you're just testing). Return to Delta. Paste a script or browse the Script Hub, then click the big green Execute button. You should see the script's GUI appear in-game within 2-3 seconds.
Part 2 — Download Delta Executor on Android
The Android build requires a one-time Unknown Sources permission and a key. Total install time is about 3 minutes.
Step 1: Download the .apk
From your phone's browser, visit the official site and tap "Download APK". The file is about 18 MB. Your phone may ask if you want to keep the .apk — say yes. The filename is delta-executor-v2.738.apk.
Step 2: Enable Install from Unknown Sources
When you tap the downloaded .apk, Android will block the install with a message like "For your security, your phone is not allowed to install unknown apps from this source". Tap Settings, toggle "Allow from this source" on, and press the back arrow. Android will return to the install prompt — tap Install.
On Android 13+ the exact wording is "Install unknown apps" and the toggle is per-browser rather than global. Toggle it on for whichever browser you used to download the APK (Chrome is most common).
Step 3: Open Delta and Tap "Get Key"
The Delta icon appears in your app drawer. Open it. You'll see a button labeled "Get Key". Tap it — a link is automatically copied to your clipboard.
Step 4: Complete the Key Verification
Switch to your browser, paste the copied link into the address bar, and hit go. You'll land on a short landing page with a "Continue" button. Tap it, then tap "Proceed to Target". After a 30-second free verification, a 32-character key appears on screen and is copied to your clipboard.
Step 5: Paste the Key into Delta
Return to Delta, paste the key into the unlock prompt, and tap Continue. The editor unlocks and stays open for 24 hours. When the key expires, repeat the cycle — it's the same flow every time.
Step 6: Open Roblox and Inject
Open Roblox, join your game, return to Delta, paste your script, and hit Execute. The script GUI appears in-game within a few seconds.
Part 3 — Install Delta Executor on iOS (iPhone / iPad)
Apple doesn't allow third-party script injectors in the App Store, so Delta's iOS build is distributed as an .ipa file that you sideload. The most popular tool for this is AltStore, which is free and works on Windows or macOS.
Step 1: Install AltServer on Your PC or Mac
Visit altstore.io, download AltServer for your operating system, and install it. On Windows, AltServer appears in the system tray. On macOS, it appears in the menu bar. Plug your iPhone into your computer with a Lightning or USB-C cable.
Step 2: Trust the AltStore Profile on iPhone
On your iPhone, open Settings → General → VPN & Device Management. Tap the Apple ID listed under "Developer App" and trust it. This lets AltStore install apps on your device.
Step 3: Download the Delta .ipa
From your phone's Safari browser, download the Delta IPA from the official site. The file is about 22 MB and saves to your Files app.
Step 4: Install via AltStore
Open AltStore on your phone. Tap "My Apps" → tap the + icon in the top-left → navigate to the downloaded Delta .ipa → tap it. AltStore signs the IPA with your Apple ID and installs it to your home screen in under a minute.
Step 5: Trust the Delta Profile
On iPhone, go to Settings → General → VPN & Device Management, find the Delta profile, and tap Trust. Now the Delta app opens normally.
Step 6: Get the Key and Execute
The Delta key flow on iOS is identical to Android — tap "Get Key", complete the 30-second verification, paste the key back, and the editor unlocks. Open Roblox, join a game, paste a script, hit Execute. Same result, same 0.3% ban rate.
Note: AltStore-signed apps expire every 7 days and need to be re-signed. Just plug your phone into your PC/Mac and AltStore re-signs it automatically as long as AltServer is running. If you want a permanent install, use TrollStore on supported iOS versions (15.0 - 15.4.1).
Common Installation Problems (and Fixes)
"Windows Defender deleted the .exe immediately." You forgot the exclusions step. Re-download, add C:\DeltaExecutor\ to exclusions first, then run the installer.
"Android says 'App not installed'." You have an old version still on your phone. Uninstall any previous Delta build, then re-install the new APK.
"iOS says 'Untrusted Developer'." Go to Settings → General → VPN & Device Management, find the Delta profile, and tap Trust.
"The key verification page won't load." Your regional ISP may be blocking the verification domain. Switch to mobile data, or use a VPN-enabled browser.
"Delta opens but Roblox crashes when I execute." Roblox pushed an update and Delta hasn't auto-patched yet. Wait 2-6 hours and update Delta.
You're Done — Now What?
Once Delta is installed on your platform of choice, you can paste any Lua script into the editor and hit Execute. If you don't want to write scripts yourself, open the built-in Script Hub and browse 4,500+ community-verified scripts for Blox Fruits, Pet Simulator X, Da Hood, Arsenal, Brookhaven, Doors, and dozens more games. Load any script with a single tap.
