通过 .MSI 安装时未加载 VSTO 插件答案

【问题标题】：VSTO plugin not loading when installed via .MSI通过 .MSI 安装时未加载 VSTO 插件

【问题描述】：

我创建了一个 VSTO Outlook 插件，它在使用 ClickOnce 部署和通过 ClickOnce 生成的 Setup.exe 安装时工作正常。现在，我已经使用 Wix 为它创建了一个 MSI。我正在使用批处理文件在注册表中添加 vsto：

@echo off
setlocal enabledelayedexpansion
%SystemRoot%\system32\reg.exe ADD "HKCU\Software\Microsoft\Office\Outlook\Addins\MyPlugin" /v "FriendlyName" /t REG_SZ /d "MyPlugin"
%SystemRoot%\system32\reg.exe ADD "HKCU\Software\Microsoft\Office\Outlook\Addins\MyPlugin" /v "Manifest" /t REG_SZ /d "file:///C:/Program Files (x86)/MyPlugin/MyPlugin.vsto"
%SystemRoot%\system32\reg.exe ADD "HKCU\Software\Microsoft\Office\Outlook\Addins\MyPlugin" /v "Description" /t REG_SZ /d "MyPlugin"
%SystemRoot%\system32\reg.exe ADD "HKCU\Software\Microsoft\Office\Outlook\Addins\MyPlugin" /v "LoadBehavior" /t REG_DWORD /d 3
endlocal

当我运行 msi 时，此注册表项已按预期添加。但是当我加载 Outlook 插件时，它处于非活动状态。 LoadBehavior 值从 3 变为 2。在 Outlook 应用程序中，LoadBehavior 为Not Loaded. A runtime error ocurred during the loading of the COM Add-in。

我试图从Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Resiliency\DisabledItems 中删除所有项目，但我的 Outlook 插件仍然没有加载。我花了很多时间尝试不同的解决方法，但都没有奏效。请帮助我如何解决此问题并成功加载 vsto 插件？

【问题讨论】：

您可以在记事本中打开您的 VSTO 文件以验证它没有损坏吗？
是的，我可以在记事本中打开 vsto
看起来还可以吗？
这是一个 XML 文件，每个标签中分配的值看起来都很好。
文件看起来和预期的一样。如果你能告诉我应该寻找哪个标签，我可以在这里分享。我不太了解 vsto 和清单文件

标签： outlook vsto outlook-addin

【解决方案1】：

我将 .NET Framework 版本从 4.7.2 降级到 4.6.1，并在 VS2019 中将 Target Platform 和 Build Platform 从 Any CPU 更新为 ```x86``。进行此更改后，我能够在 Outlook 中加载加载项。

【解决方案2】：

我知道这有点老了，但如果这个问题不断发生，这里有另一种解决方案。如果您在 Outlook vsto 中创建表单区域，则需要在此处的注册表中声明它们：

Ordinateur\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\FormRegions\IPM.Note

我的插件叫做“AddinK”，所以我需要创建注册表编辑器键

Ordinateur\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\FormRegions\IPM.Note

我在其中添加了两个名为“myname”和“itsname”的表单区域，方法是创建 2 个名为 REG_SZ 的值

AddinK.myname

和

AddinK.itsname

有值

=AddinK
