摘要

The VSE installation log might contain a generic error code 255 that references the SystemCore part of the product installation. The VSE file SetupVSE.exe invokes the executable Mfehidin.exe that controls the installation of core components and waits for the return code. The error 255 is a fatal error return code from Mfehidin.exe that can have numerous causes.
