Question

我正在使用Excel开发Add-In Visual Studio 2017。在registry中，我意外删除了与Excel Add-In相关的文件夹，因为我无法让Excel忘记已禁用的Add-In。抱歉，我含糊不清，但我不记得确切的详细信息，也许这甚至不是原因。

现在，启动Excel时总是弹出错误消息：：

我认为使用官方安装程序修复Office或Visual Studio也可以解决此问题，但不能解决。如何修复与此Add-In错误相关的注册表？也许堆栈跟踪可以帮助您找出答案。

注意：文件夹C:/Program Files (x86)/Microsoft Visual Studio 12.0不存在，但是存在10.0和14.0以及没有版本号的文件夹，因此安装程序可以指向其他位置吗？

答案来晚了，我今天在Excel Office 2013上遇到了同样的问题。我通过删除add-in解决了这个问题。

以管理员身份打开Excel
创建一个新文档
点击developer标签
点击COM add-ins
找到add-in，它将帮助您了解显示add-in路径的那一个

如果您需要此add-in，则必须重新安装。
