Here is a step-by-step guide to fixing TeknoParrot Error 4.

9) Dependency walker & advanced diagnosis

Use tools like Dependencies (modern Dependency Walker) to open the failing DLL and see which sub-dependencies are missing. This shows missing system DLLs or incorrect architectures.
Look for red-highlighted entries (missing) and note required runtimes or system DLLs.

Q: I disabled my antivirus, but I still get Error 4.

A: Windows Defender has Real-time protection AND Cloud-delivered protection AND Automatic sample submission. Disable all three.

The Fix: Resolving TeknoParrot "Failed to load DLL Error 4"

The Diagnosis If you are encountering "Failed to load DLL Error 4," the issue is almost certainly a missing dependency rather than a corrupt game file. TeknoParrot acts as a loader for arcade games, and it relies on specific Windows multimedia libraries to function. Error 4 specifically indicates that the system cannot locate or load the XAudio sound library.

The Solution You do not need to reinstall TeknoParrot. You need to install the Microsoft DirectX End-User Runtimes.

Download the DirectX End-User Runtimes: Go to the official Microsoft website and download the "DirectX End-User Runtimes (June 2010)" installer. This package contains the legacy DLL files (specifically XAUDIO2_7.dll or similar variants) that TeknoParrot calls upon. 9) Dependency walker & advanced diagnosis
Run the Installer: Execute the dxwebsetup.exe file. It will prompt you to choose a directory to unpack temporary files; the default location is fine. Once unpacked, the actual installation wizard will begin.
Complete the Installation: Follow the prompts to install the libraries. Even if you have a modern version of DirectX installed on Windows 10 or 11, this step is necessary because modern Windows versions strip out older, "legacy" DLL files that older arcade games require.
Restart: Restart TeknoParrot and launch your game. The loader should now successfully locate the required DLL.

Summary Error 4 is a "Missing Dependency" error. By installing the DirectX End-User Runtimes, you restore the missing XAudio components, allowing the emulator to bridge the gap between the arcade software and your PC's hardware.
