Install errors
| Message | Platform | What it means | Fix |
|---|---|---|---|
| App not installed: package appears to be invalid | Android | Signature clash with an existing copy, or a corrupt download | Full fix |
| There was a problem parsing the package | Android | Incomplete download, or the APK targets a newer Android | Re-download on a stable connection |
| Blocked by Play Protect | Android | Google is blocking a sideloaded executor | Disable Play Protect scanning for the install |
| Installation blocked for security reasons | Android | Unknown sources not allowed for that browser | Allow install from that specific app |
| Untrusted Enterprise Developer | iOS | The signing profile has not been trusted yet | Settings → General → VPN & Device Management → Trust |

Key errors
| Message | What it means | Fix |
|---|---|---|
| Key expired | Older than roughly 24 hours | Generate a new one |
| Invalid key | Miscopied, or never registered server-side | Use the Copy button; disable bypass tools |
| Key not found | The checkpoint never completed validation | Re-run the checkpoint with blockers off |
| Checkpoint will not load or loops | Ad-blocker or DNS filtering | Try mobile data, disable blockers |
All four are covered in detail on the key troubleshooting guide.
Injection errors
| Symptom | What it means | Fix |
|---|---|---|
| Status stays "Not Injected" | Attach never succeeded | Check launch order first |
| Attach does nothing at all | Roblox opened before Delta, or not fully loaded | Injection guide |
| Delta closes when you press Attach | Antivirus intervened, or no admin rights | Exclude the folder; run as administrator |
| Injects, but scripts do nothing | Build does not match the current Roblox client | Update Delta, or wait for the rebuild |
| Roblox closes right after injecting | Anti-cheat detected the attach | Stop using that account — see ban risk |
Roblox errors people blame on Delta
These come from Roblox, not the executor. Fixing Delta will not help.
| Message | What it actually is | Fix |
|---|---|---|
| Roblox Upgrade — your version of Roblox is out of date and will not work properly | The Roblox client needs updating | Update Roblox from the Play Store or App Store |
| Error code 280 | A client or connection problem on Roblox's side, commonly seen after a client update | Update Roblox, restart, then retry |
| An unexpected error occurred | Generic Roblox connection failure | Check status.roblox.com |
If Roblox alone misbehaves with Delta uninstalled, the problem was never the executor.
Antivirus detections
| Detection name | What it means |
|---|---|
| Trojan:Win32/Wacatac | Generic Defender heuristic. Common and expected on executors. |
| PUA:Win32/GameHack | Correctly identifies it as a game-modification tool. Not a payload. |
| HackTool / Riskware | Behaviour classification, not malware detection. |
| Named stealers or miners | A real threat. Delete the file — you have a bad reupload. |
How to tell these apart properly: reading a virus scan.

Frequently asked questions
What is Roblox error code 280?
A Roblox-side client or connection error, seen most often just after a client update. It is not caused by Delta — update Roblox, restart and try again.
Is "Trojan:Win32/Wacatac" a real virus in Delta Executor?
It is a generic Windows Defender heuristic, and it appears on many executors because of how they inject. It is not evidence of a payload on its own, though it is not a clean bill of health either.
Why do I get the Roblox Upgrade popup with Delta installed?
That message comes from Roblox saying its own client is out of date. Update Roblox from your app store; it is unrelated to the executor.
What does "Untrusted Enterprise Developer" mean on iOS?
The app is signed with a certificate your device has not trusted yet. Approve it under Settings, General, VPN and Device Management.
