Please try to remove the file C:\WINDOWS\inf\infcache.1
To do so, please click start -> cmd.exe and type in the appeared window "del C:\WINDOWS\inf\infcache.1" (without quotes)
Warning! This is Windows XP only solution. This should never be done on any other system (like Vista)
如果以上方式不管用可以尝试暂停杀毒软件，包括360之类的。
