windows7上，python2.7操作ie浏览器时，PAM30报错：pywintypes.com_error?

Question

如果在运行如上代码前，先打开一个 ie 浏览器，就正常运行，不会报错。
但是，如果不事前打开一个 ie 浏览器，直接运行如上代码，就会报错。
请大家看看是什么原因？
怎么弄好呢？

环境：
windows7 64位
python 2.7.12 32位
代码：

from PAM30 import PAMIE  
def d():  
  ie = PAMIE()  
  ie.navigate('http://pamie.sourceforge.net/pamieform.html')  

报错信息如下：

Traceback (most recent call last):

d()
  File "D:/jianguoyun/pythonProgrames/myModule/test/pamieTest/pamie-f.py", line 9, in d
ie = PAMIE()

Answer 1

导入如下注册信息，就可以正常调用了：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREWow6432NodeClassesCLSID{0002DF01-0000-0000-C000-000000000046}LocalServer32]
@=""C:\Program Files (x86)\Internet Explorer\iexplore.exe""

[HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{0002DF01-0000-0000-C000-000000000046}LocalServer32]
@=""C:\Program Files\Internet Explorer\iexplore.exe""

Answer 2

看来是找不到InternetExplorer.Application这个类,预计是你的IE版本不为默认的IE8
