其实 很早以前就从这里下载了msn最新的9.0中文版，还包括其他的比如livewriter等等..但是在运行最新版时老是出现一个问题。那就是会弹出来个对话框，显示
无法定位程序输入点 _except_handler4_common 于动态链接库 msvcrt.dll 上
这个比较郁闷。虽然说倒是不影响什么，但是老弹就弄的人心烦，今天又时间就来解决一下这个问题。本方法开始搜索于互联网，这是英文原文：
Volker:
Thank you so much for sharing this finding!!! After installing my
Creative Sound card that came with a pack of XP and Vista drivers —
I had the :
The procedure entry point except handler4 common could not be located
in the dynamic link library msvcrt.dll
while using my Safari browser (when minimizing/maximizing windows) and
with Photoshop CS3 — the programs ran okay — but the error was a
great annoyance —-
After long hours of searching for solutions — including XP repair
(which I avoided) — I found your post!
I searched my drive and found of dwmapi.dll file in my system32
directory and renamed it (in case I needed to recover it.
Now the error is gone!!! In my case the error was called by the
dependency call in the dwmapi.dll .
I really, really, really appreciate you letting us know about this !!!
It’s a bad situation when new software trys to accommodate more than
one operating system — and the .dll dependencies conflict — these
errors are truly a nasty situation!
Thanks again!!!
后来经过研究，现在得出解决方法。
大概的意思：当运行“Safari browser”最大化和最小化，及运行photoshop cs3会出现这个问题；
这是由于sp3加载的驱动造成的；只需要将dwmapi.dll重新命名一下即可以解决；
按照这个思路，我在system32中找到dwmapi.dll，试着把“dwmapi.dll”重命名一下（改成任意文件名）；问题得到解决。yeah.~~
