COMException was caught:

Retrieving the COM class factory for component with CLSID {71944DD6-B5D2-4558-AD02-0435CB2B39DF} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

推荐答案

该计算机上没有注册该CLSID的类。我想你只是忘了安装设备附带的软件。通常，您可以安装驱动程序磁盘上包含的其他软件，其中还包括使用自定义软件控制设备的组件和类。也许它甚至有一个可再发行的包。看看吧。



祝你好运！

There is no class registered on that machine with that CLSID. I think you simply forgot to install the software that came with the device. Often you can install additional software that is included on the driver disk, which also includes components and classes for controlling the device using custom software. Maybe it even got a redistributable package of it. Check it out.

Good luck!
