推荐答案

这是我解决此问题的方法：

我正在使用Win 7 64位和Office 2007

I'm using Win 7 64bit and Office 2007

运行程序 dcomcnfg -32 。 （如果单词和excel组件运行在64位以下，则找不到该词）

Run program "dcomcnfg -32". ( You cant find the word and excel components if it runs under 64bit)

转到控制台根目录/组件服务/计算机/我的电脑/ DCOM配置/
查找Microsoft Word和Excel并选择属性。

Go to "Console Root/Component Services/Computer/My Computer/DCOM Config/" Look up Microsoft Word and Excel and choose properties.

转到安全性，然后在配置权限下选择自定义。（如果需要，您可能需要更改其他权限以及，但我不需要）
添加 IIS_IUSRS并赋予它完全控制权限。

Go to Security and select "Customize" under "Configuration Permissions. (If needed you might want to change the other permissions as well, but I didn't need to) Add "IIS_IUSRS" and give it "Full Control".

现在转到 Identity并选择交互式用户。

Now go to "Identity" and select "The interactive user".

完成后不要忘记按 OK。：D

Do not forget to press "OK" when done. :D

希望这对您有帮助，对其他人也有帮助。
