Some community members have created an all-in-one script, Install_all.bat , that automates the installation of all Visual C++ Redistributable packages from 2008 onward. This can be found in some all-in-one runtime packages and ensures no version is missed, which has resolved the error for many users.

A frequently overlooked aspect is User Account Control (UAC) and file permissions. Modern Windows versions restrict write access to system-critical folders. If a user places their arcade games inside the Program Files or Program Files (x86) directories, Windows will restrict the game's ability to create or modify the log files and configuration DLLs it needs to function. This restriction prevents the game from loading the necessary libraries, manifesting as Error 4. The solution is to move the entire game directory to a neutral location, such as C:\Games or D:\Arcade , where the user has full read/write permissions. Running the TeknoParrot_ui.exe as an Administrator is also standard protocol to bypass UAC restrictions during the injection phase. TekParrotUI
By systematically whitelisting your folders, restoring quarantined DLLs, and running the loader as an administrator, you will conquer this error. Do not feel defeated if the first fix doesn't work. Emulation requires a balance of tweaking and patience.
