the exact message is
Error al intentar ejecutar el proyecto : No se puede cargar el archivo o ensamblado '86/87a' ni una de sus dependencias.El nombre de ensamblado o el codigo base dado no es valido(Excepcion de HRESULT 0X80131047)
and i translated and put it in the past message , i put it again wiht the name of my assembly and exception HRESULT
Here you are
>" Error attempting to execuute this project the file or assmebly '86/87a' could not be loaded neither one of their dependencies.The name of hte assembly or base code is not valid (Exception of HRESULT 0X80131047)"
