我已经修改了 pywin 包演示，该演示创建了一个用于 excel 功能区栏的按钮。按下按钮后，所选文本将在命令行中运行，所选文本将被输出替换。

使用不同的 clsid 文件名组合注册程序时出现问题。我无法更改代码的 clsid 和/或文件名。如果我创建此文件的副本，修改并注册它，运行的 COM 对象是原始的 excelAddin.py，而不是我新修改的文​​件。我现在缺少 COM 注册过程中的一个步骤。我应该在哪里添加哪一行？

gencache.EnsureModule('{00020813-0000-0000-C000-000000000046}', 0, 1, 3, bForDemand=True) # Excel 9
gencache.EnsureModule('{2DF8D04C-5BFA-101B-BDE5-00AA0044DE52}', 0, 2, 1, bForDemand=True) # Office 9
