01 / DIRECT ANSWER
How do I fix “Injection done” but no FC 26 overlay?
Test visibility, compatibility and isolation in that order. Each step removes one entire class of causes.
02 / MESSAGE SEMANTICS
Is “Injection done - shutdown” an error?
No—not by itself. In the complete public launcher log, the line is followed by normal Launcher cleanup: uninstalling the fake EAAC file and restoring the original.
Issue #41 is useful for sequence semantics, not as a healthy compatibility example: its game build 1.0.137.49763 and editor v26.3.4 are not a pair in the current official manifest. That build maps to v26.3.5.
03 / SUCCESS STATE
What should a working overlay look like?
The Live Editor UI is drawn inside FC 26. The official Wiki illustration shows a top menu bar, initialization dialog and logger panel; F9 opens or hides this menu.
The current Getting Started Wiki screenshot uses an older FC-era UI as an illustration, so it defines the interface pattern—not proof of the current FC 26 build. The current Editing Player instructions independently confirm F9 as the menu hotkey.
04 / INTERACTIVE DIAGNOSIS
Which missing-overlay branch matches my attempt?
Choose only observations from the same launch. The decision tree runs locally and routes the next evidence—not a speculative cause.
05 / VISIBILITY CHECK
How should I test the F9 hotkey?
Make the smallest possible input test. F9 is documented by the creator; most keyboard-mode theories are not.
06 / TWO SIGNALS + ONE GATE
How do I verify injection without overreading the log?
Read the newest log from one attempt. Two lines establish the launcher handoff; the manifest decides whether that attempt was supported.
07 / CONTROL ATTEMPT
How do I run Live Editor without other integrations?
Keep the mapped editor, remove the other launch layers. v26.3.1 added a Launcher “No Mods” checkbox specifically useful for this control.
08 / IF CLEAN WORKS
What if the overlay returns in the clean test?
You now have a working baseline—not a universal fix. One removed layer changes the outcome.
The first layer that makes the overlay disappear owns the next investigation. Return to the last working state; do not reinstall the base game or edit injector offsets when the clean control already proves the overlay path works. If Mod Manager is that layer, open the combined integration diagnosis.
09 / IF CLEAN STILL FAILS
What if a mapped, clean attempt still has no overlay?
Treat it as a genuine overlay-path failure and preserve the state needed for a maintainer to reproduce it.
10 / ATOMIC SCOPE
When is this the wrong troubleshooting page?
“No overlay” is exact only when FC 26 remains open and usable. Route the observed failure, not the phrase copied from a search result.
11 / FALSE-FIX FILTER
Which no-overlay “fixes” should I avoid?
Exact-topic search results are heavily polluted by unofficial environments and unconfirmed tracker guesses.
12 / REPRODUCIBLE REPORT
What should I report if the overlay remains missing?
Include the signals that distinguish launcher completion from in-game UI initialization.
13 / EVIDENCE
Sources and verification boundaries
Creator documentation and the live manifest control behavior and compatibility. Tracker cases and videos are used to classify symptoms and reject false fixes—not to manufacture certainty.
Canonical Run Game sequence, expected in-game overlay at the main menu, Mod Manager isolation workflow and automatic EAAC restoration when Launcher closes.
Primary documentation for pressing F9 to open the Live Editor menu after loading the game mode.
Exact FC26.exe build → accepted Live Editor range. It exposes the historical issue #41 pair as unmapped rather than healthy.
No Mods control added in v26.3.1 and current UI/font changes; no claim of a universal missing-overlay fix.
Real order from Game Window Found to Injection done, Launcher shutdown, fake EAAC uninstall and original restoration. Stage semantics only; the pair is historically unmapped.
Adjacent blank-window/no-overlay report in a nonstandard environment. Its config workaround is not maintainer-confirmed and is excluded.
Current crash/error report showing why offset deletion and disabling startup overlay are not general no-overlay instructions; no maintainer-confirmed resolution.
The transcript shows the audience-visible F9 interaction around 10:42; creator Wiki documentation controls the factual instruction.
Exact-topic search result targeting an unofficial config/DLL path. Audited and rejected as guidance for the official launcher.
First-party location for a specific Defender event; not evidence for disabling protection or adding blanket exclusions.
Checked: 11 August 2026 against two official Wiki pages, the live manifest, changelog, three public issues, Microsoft Help and two locally normalized video transcripts.
Current reference pair: FC 26 v1.6.6 build 1.0.139.20381 → Live Editor v26.3.5–v26.3.6.
Historical-log warning: issue #41 reached Injection done using build 1.0.137.49763 + v26.3.4; the current manifest maps that build to v26.3.5.
Video boundary: a newly transcribed Portuguese exact-topic result was also excluded because it depends on an unofficial/cracked DLL-loading setup.
Review trigger: a new manifest mapping, creator overlay/hotkey documentation, changelog fix or maintainer-confirmed issue resolution.
