Our ultimate directory of Windows PC executables. RazerAppEngineUpgrade-v4.0.590.exe is an update utility for the Razer App Engine, a core background service that powers the modern Razer software ecosystem, specifically Razer Synapse 4. It is responsible for installing, patching, or upgrading the "App Engine" framework which allows Razer devices to communicate with your operating system.
You have this file because you are either installing or updating to the latest version of Razer's hardware configuration suite. Unlike older versions of Synapse, the newer architecture (Synapse 4) uses this "App Engine" to run various modular components—like Chroma lighting, Macro modules, and THX Spatial Audio—as separate sub-processes to improve stability and speed. This specific file ensures that the underlying engine is updated to support the latest firmware and features for your peripherals.
Below are 4 simple steps you can take to see if the RazerAppEngineUpgrade-v4.0.590.exe process is safe or malware.

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
