c# - 该类未配置为支持提升激活

Question

当我尝试从 Delphi 应用程序加载 COM 可见的 C#.net 程序集时，Windows Server 2012 上会弹出“该类未配置为支持提升激活”错误。

有没有办法将其配置为以编程方式支持提升激活？

目前为了避免，权限级别设置为“以管理员身份运行”。

这是 CO_E_ELEVATION_DISABLED 错误。如果该类未在注册表中正确注册提升，则可能会发生这种情况。您可以在MSDN中找到如何注册它:

The COM Elevation Moniker

The COM class must also be annotated as LUA-Enabled. This requires the following registry entry:

HKEY_LOCAL_MACHINE\Software\Classes\CLSID
  {CLSID}
    Elevation
      Enabled = 1

If this entry is missing, then the activation returns the error CO_E_ELEVATION_DISABLED.

Note that these entries must exist in the HKEY_LOCAL_MACHINE hive, not the HKEY_CURRENT_USER or HKEY_USERS hive. This prevents users from elevating COM classes that they did not also have the privileges to register.
