Marvel Rivals didn't detect — what now?
Loader says "game not found" — here's the precedence order and what to do for each launcher.
The loader scans for Marvel Rivals in this order: Steam install → Epic install → manual override (set in Settings).
If you have Steam installed, the loader reads the Steam library path from HKCU\Software\Valve\Steam. If Steam is installed to a non-default drive, make sure you've finished at least one library scan since the install — open Steam, click any library entry once.
If you have Epic installed, the loader reads LauncherInstalled.dat from C:\ProgramData\Epic\UnrealEngineLauncher\. If Marvel Rivals is on a secondary drive, Epic stores the path here and Nimbus will find it.
Manual override. In the loader's Settings tab, set Game path override to the full path to MarvelRivals.exe. This wins over auto-detection. Use this if you have a custom install (e.g. portable Steam install on an external drive).
If detection still fails, open a support ticket from your dashboard with the loader's auto-generated diagnostic log attached — it lists every path the scanner tried.
