VSTO 加载项不会在 64 位 Outlook 中加载

问题描述 投票：0回答：2

我有一个 VSTO 加载项，在 32 位或 64 位 Windows 上运行时，它可以很好地与 32 位 Outlook 一起工作，但是当它安装到具有 64-Outlook 的计算机上时，它不会加载加载项。

尝试直接从 Visual Studio 运行加载项时，出现以下错误消息。

有没有人以前见过这种行为，或者对我已经没有想法的尝试有什么建议？

重要的是 Outlook 位数，而不是 Windows - 您的插件是由 outlook.exe 进程加载的 dll，因此位数由主机进程（Outlook）的位数决定。

将您的插件编译为“任何 CPU”。如果不能，则需要提供 x86 和 x64 版本并根据 Outlook 位数安装适当的版本。

虽然普遍认为应该能够将 DLL 编译为“任何 CPU”，然后根据 Outlook 的位数应用正确的注册表项来加载 DLL，但这对我们不起作用。

我们发现 does 工作正常的是构建单独的 DLL 到 32 位和 64 位，然后为每个处理注册表条目创建单独的安装程序。
