OpenHardwareMonitorLib.dll和"Invalid pointer“或"Exception: Object reference not set to an object instance”COM错误

Question

我将使用Open Hardware Monitor库来读取有关硬件的一些值，而不是执行OpenHardwareMonitor.exe并从WMI读取，因此我使用RegAsm在注册表中注册类型(以便我可以将库中的类作为COM对象运行)。首先，我将项目的COMVISIBLE属性更改为TRUE，并使用MSBuild.exe重新编译库。我会将this脚本转换为Autoit，但当我试图调用任何方法时，我得到了错误：“无效指针”。或“异常:对象引用未设置为对象的实例”。我不明白为什么会出现这个错误，我不认为是因为RegAsm，因为它会给我一个警告，但它会注册类型，这是它添加到注册表中的内容：

这是OLEView显示的：http://i.stack.imgur.com/Oa1NO.jpg，这是生成错误的简单脚本：

在执行脚本之前，您需要在第二行检查您的.NET框架版本。This是包含脚本和库的归档文件

Answer 1

您是否尝试将#AutoIt3Wrapper_UseX64=N添加到脚本以将其作为32位COM对象运行
