Now, with certain platform exceptions, it is necessary to install the runtimes correctly as an assembly. The mini- mal runtime consists of three files: msvcr80.dll, msvcp80.dll and the manifest (Microsoft as part of a service pack. The result of installing the MSVC8 redistributable is that a shared assembly is installed on WinXP, Server2003 or MS Vista. For Windows 2000, it simply writes the two DLLs to Windows 2000 and see that advice when you follow it up in the system log. Private Assembly Installing the runtime assembly from the Microsoft redistributable is the easiest and thus the preferred way to

opção para os alunos que desejam aprender sobre arquitetura de conjunto de instruções e programação assembly, os fundamentos básicos para o trabalho com linguagens de alto nível. Este livro escrito de forma generalizado em aplicações reais. Há muito tempo, eu costumava en- sinar um primeiro curso em programação assembly e se eu estivesse fazendo isso agora, eu ficaria feliz em utilizar este livro. —John Mashey, um opcodes são apresentados em vários formatos úteis para referência rápida, facilitando a codifi- cação assembly e interpretação. Além disso, as explicações e exemplos de como utilizar a ISA tornam o trabalho
