Delta Executor Not Working: Find the Real Problem

"Not working" covers four completely different failures. Two minutes narrowing down which one you have will save you an hour of trying random fixes.

Version v2.735 Updated

Work out which stage is failing

Answer these in order and stop at the first "no".

QuestionIf no, your problem isGo to
Does Delta install and open?An install failureApp not installed
Does the key get accepted?A key failureKey not working
Does it stay open, no crash?A stability failureSection below
Does Attach report success?An injection failureNot injecting
Do scripts actually run?A version mismatchSection below

Each of those has a different fix. Trying an injection fix on a key problem is why people spend an afternoon getting nowhere.

Is Delta down, or is it just you?

Delta's key checkpoint and script hub are online services, so they can go down independently of the app. If the key page will not load at all, or the script hub is empty when it normally is not, the problem may not be yours.

Two quick checks before you reinstall anything:

  • Try the key checkpoint on mobile data instead of Wi-Fi. If it loads, your network was filtering it.
  • Check whether Roblox itself updated today. A fresh client update takes every executor offline for a day or two, and no reinstall fixes that — you wait for the rebuild.

Roblox publishes its own service state at status.roblox.com, which is worth a glance when everything seems broken at once.

Delta opens then closes immediately

A crash within a few seconds of launch usually means one of three things.

  1. Not enough free memory. Close other apps. Delta and Roblox running together is demanding on older phones.
  2. A partial install. Uninstall fully, restart the device, reinstall. Installing over the top of a broken copy keeps the broken parts.
  3. An unsupported device. Very old Android hardware and 32-bit devices tend to install fine and crash on launch.

It attaches but scripts do nothing

This is the most misdiagnosed case. Injection reports success, no error appears, and the script simply has no effect in-game.

That points at a version mismatch: your Delta build attached to a Roblox client it does not fully understand. Update Delta to the current release. If you are already current, the rebuild has not shipped yet.

The other possibility is the script itself. Community scripts break constantly as games update, and a broken script is not an executor fault. Try a trivial one first — a simple print — to prove execution works before blaming Delta.

Still stuck after all of that

Do a genuinely clean reinstall, in this order:

  1. Uninstall Delta.
  2. Clear your browser cache and cookies, which the key flow depends on.
  3. Restart the device.
  4. Reinstall the current build from the download hub.
  5. Generate a new key on the clean install.
  6. Launch Delta, then Roblox, then attach after the game loads.

If that still fails and Roblox updated recently, you are waiting on the developers. That is a real answer, and it is more honest than a sixth reinstall.

Frequently asked questions

Why is Delta Executor not working today when it worked yesterday?
Almost always a Roblox client update. Executors stop working until a matching build ships, usually a day or two later. Nothing on your device is broken.
How do I know if Delta Executor is down?
If the key checkpoint will not load at all, or the script hub is unexpectedly empty, the service side may be down. Try mobile data first to rule out network filtering.
Delta opens and closes straight away. What is wrong?
Usually low free memory, a partial install, or unsupported hardware. Close other apps, then uninstall fully, restart and reinstall rather than installing over the top.
Delta says it injected but nothing happens in the game. Why?
Either your build does not match the current Roblox client, or the script itself is broken. Test with a simple print script to confirm execution works before blaming the executor.
How long after a Roblox update until Delta works again?
Typically a day or two, though there is no guarantee. Until a matching build is released there is no fix on your side.
