关掉了杀毒软件360，在华硕笔记本上（WINDOWS XP PROFESIONAL环境）安装STEP5 V7.2，一路顺风完成了。然后授权。
运行STEP5出现错误：
S5_VDD ERROR!
S5_VDD can not creat process VDDLOOK.EXE.
File does not exist in %S5_SYSTEM%,
or DLL does not exist in %SystemRoot%\SYSTEM32or wrong environment variable S5_SYSTEM

You can not use STEP 5, because S5_VDD can not communicate with s5 drivers (PROMMER / AS511)!

怎么办啊？很急啊。
