我有一个Excel VSTO加载项没有安装在我的一台用户机器上。它到目前为止安装在其他人的机器上（8台机器），但在这台特定的机器上，它提供了以下错误消息。Excel VSTO加载项错误 - 无法创建应用程序域

我不知道为什么我会得到这个错误。从谷歌搜索'，没有什么是从一个可敬的来源返回。我让用户验证.NET 3.5已安装，以管理员身份运行它，但似乎没有任何帮助。
我有一个安装程序，它自动将插件从注册表挂钩到excel，但是如果安装了VSTO，则会出现相同的错误消息。
我不明白这个错误信息告诉我什么。谁能帮我吗？
我不能让我的项目类型项目.NET 3.5客户端配置文件。 “尝试重新定位项目已被取消。您选择的.NET Framework版本不受此项目类型的支持。”是因为我正在使用外部COM库吗？ – Smeiff
只需确认：您的项目已经瞄准了整个框架并且无法切换到客户端配置文件？ （仅供参考，外部COM库可能不是问题。） – Keith
正确，它当前是.NET 3.5（不是客户端配置文件），我无法将其切换到客户端配置文件。 – Smeiff
