Error Description
Delta Executor opens but fails to inject into Roblox — scripts cannot execute.
Why This Happens
- 1Delta Executor version is outdated and incompatible with the latest Roblox client
- 2Roblox recently updated its anti-cheat system (Byfron/Hyperion), requiring a Delta patch
- 3Antivirus or Windows Defender is blocking the injection DLL files
- 4Delta is not running with administrator privileges (PC)
- 5Missing system dependencies — Visual C++ Redistributables or .NET Framework (PC)
- 6Corrupted app cache or incomplete installation files
- 7Roblox has not fully loaded before injection was attempted
- 8Network instability preventing Delta from downloading required components
- 9iOS certificate has expired or been revoked by Apple
- 10Background security apps or RAM cleaners are interfering with the injection process
Quick Fix — Try This First
These 3 steps resolve the issue for most users. If they don't work, continue to the detailed platform-specific guide below.
Uninstall Delta Executor completely, then download and install the latest version from deltaexecutor.co/download
On PC: Right-click Delta Executor → Run as Administrator. On Android: Clear app cache in Settings → Apps → Delta → Storage
Wait for Roblox to fully load into a game before clicking Inject — do not inject from the Roblox home screen
How to Fix on Android
7 steps — follow in order until the issue is resolved.
Update Delta Executor to the Latest Version
The most common cause of injection failure on Android is running an outdated version. Go to deltaexecutor.co/download/android, download the latest APK, uninstall the old version first, then install the new one. Do not install over the old version — always do a clean install.
Clear App Cache and Data
Go to your phone Settings → Apps → find Delta Executor → Storage → tap "Clear Cache" and "Clear Data". This removes corrupted temporary files that can prevent injection. After clearing, you will need to re-enter your key.
Use the Built-in Fix Tool
Open Delta Executor, go to Settings (gear icon) → tap "Delta Fixes" → select "Install Dependencies". This downloads and installs the required libraries for injection. Wait for the process to complete, then restart the app.
Grant All Required Permissions
Delta Executor needs storage and overlay permissions to function. Go to Settings → Apps → Delta Executor → Permissions and enable all requested permissions. On Android 11+, also grant "Allow management of all files" in special app access.
Check Your Internet Connection
Injection requires a stable internet connection to verify your key and download script dependencies. Switch between Wi-Fi and mobile data to test. If you are on a school or work network, try using mobile data instead — some networks block executor traffic.
Disable Battery Optimization
Android may kill Delta Executor in the background during injection. Go to Settings → Battery → Battery Optimization → find Delta Executor → select "Don't optimize". This prevents the OS from interrupting the injection process.
Reinstall Roblox
Sometimes the issue is with Roblox, not Delta. Uninstall Roblox, clear its cache, then reinstall from the Play Store. Launch Roblox first, join a game, then switch to Delta and inject.
How to Fix on PC (Windows)
8 steps — start with Step 1 (most common fix).
Run Delta Executor as Administrator
Right-click the Delta Executor shortcut or .exe file and select "Run as administrator". DLL injection requires elevated privileges on Windows. If this works, you can set it to always run as admin: right-click → Properties → Compatibility → check "Run this program as an administrator".
Whitelist Delta in Windows Defender
Windows Defender frequently quarantines executor DLL files, causing injection to fail silently. Open Windows Security → Virus & threat protection → Manage settings → Exclusions → Add an exclusion → select the entire Delta Executor folder. Also check Quarantine history — if Defender already removed a DLL, you need to restore it and then add the exclusion.
Reinstall DLL Files via Delta Settings
Open Delta Executor → Settings → Delta Fixes → click "Reinstall DLL". This re-downloads the injection DLL from the server. If the DLL was deleted by antivirus, make sure you have added the exclusion first (Step 2) before doing this.
Install Visual C++ Redistributables
Delta Executor requires Visual C++ 2015-2022 Redistributable (both x86 and x64 versions). Download them from Microsoft's official website. Install both versions, restart your PC, then try Delta again. Missing VC++ is one of the most overlooked causes of injection failure.
Install .NET Framework 4.8+
Some Delta components require .NET Framework. Download .NET Framework 4.8 from Microsoft if you do not have it. On Windows 10/11, it should be pre-installed, but some modified Windows installations may have removed it.
Enable Developer Mode in Windows
Go to Settings → Update & Security → For developers → toggle "Developer mode" to On. This allows Delta to perform DLL sideloading without additional security prompts. Restart your PC after enabling.
Check 32-bit vs 64-bit Compatibility
Make sure you downloaded the correct version of Delta Executor for your system. If you have a 64-bit Windows (most modern PCs), use the 64-bit version. Mismatched architecture will cause injection to fail with no clear error message.
Disable Third-Party Antivirus Completely
If you use antivirus software beyond Windows Defender (Norton, McAfee, Avast, Kaspersky, etc.), temporarily disable it entirely. Some antivirus programs hook into the same system APIs that Delta uses for injection, causing conflicts even if Delta is whitelisted.
How to Fix on iOS
4 steps for iPhone and iPad.
Re-sideload the Latest IPA File
iOS injection failures are almost always caused by an expired or revoked certificate. Download the latest Delta Executor IPA from deltaexecutor.co/download/ios and re-sideload it using Sideloadly, AltStore, or ESign. Make sure you use the same Apple ID that was used for the original sideload.
Trust the Developer Certificate
After sideloading, go to Settings → General → VPN & Device Management → find the developer profile for Delta Executor → tap "Trust". If the certificate does not appear here, the sideload may have failed — try again.
Check Certificate Expiration
Free Apple Developer certificates expire after 7 days. If you sideloaded more than 7 days ago, you need to re-sideload. Consider using a paid Apple Developer account ($99/year) for 1-year certificates, or use a signing service like ESign for longer validity.
Disable VPN and Check Network
Some VPNs interfere with the injection handshake on iOS. Disable any VPN, switch to a stable Wi-Fi connection, and try again. If you are on a restricted network (school, work), try using your phone's hotspot instead.
How to Prevent This Issue
Always keep Delta Executor updated to the latest version — enable update notifications in the app settings
Add Delta Executor to your antivirus exclusion list before the first launch to prevent DLL quarantine
Wait for Roblox to fully load into a game before attempting injection — never inject from the home screen
Bookmark deltaexecutor.co/status to check server status before troubleshooting — the issue might be a known outage

Frequently Asked Questions
The most common causes are: outdated Delta version, antivirus blocking the DLL files, missing Visual C++ Redistributables (PC), or Roblox updated and Delta needs a compatibility patch. Follow the platform-specific steps in this guide to resolve it.
Temporarily disabling antivirus is safe if you downloaded Delta from the official website (deltaexecutor.co). We recommend adding Delta to your antivirus exclusion list instead of fully disabling it. Delta is regularly scanned with VirusTotal showing 0 detections.
The Delta development team typically pushes a compatibility patch within 4-8 hours of a major Roblox update. Minor Roblox updates rarely cause injection issues. Check our status page or Discord for the latest update timeline.
Loading screen freezes are usually caused by network issues or injecting too early. Force close both Delta and Roblox, restart your device, launch Roblox first, wait until you are fully in a game, then switch to Delta and inject.
Yes, Delta Executor is fully compatible with Android 14 and 15. If you experience issues on these versions, make sure you have granted all permissions (including "Allow management of all files") and disabled battery optimization for Delta.
Crashes during injection on PC are usually caused by missing VC++ Redistributables or corrupted DLL files. On Android, crashes are typically from corrupted cache — clear app data and reinstall. On iOS, crashes mean the certificate has expired.
Open Delta Executor → Settings → Delta Fixes → "Reinstall DLL". If this does not work, add the entire Delta folder to your antivirus exclusions first (Windows Defender may have quarantined the DLL), then try reinstalling the DLL again.
No. DLL injection requires administrator privileges on Windows. You must right-click Delta Executor and select "Run as administrator" every time, or set it to always run as admin in the Properties → Compatibility tab.
