我正在使用的VisualStudio发明packandgo dll库。

I am using Inventor packandgo dll library in visualstudio.

任何人都知道什么是错误？

Anyone know what is the error?

推荐答案

一些地方在你使用的是code，有打电话给Win32 API的，的 CoCreateInstance的，动态加载DLL并从中实例化一个对象。

Some where in the code you are using, there call to the Win32 API, CoCreateInstance, to dynamically load a DLL and instantiate an object from it.

组件ID和DLL，它能够实例化对象之间的映射通常见于HEKY_CLASSES_ROOT \ CLSID在注册表中。为了进一步讨论这个问题是解释了很多有关的 COM在Windows 。但是错误指示COM GUID是不是present在注册表中。

The mapping between the component ID and the DLL that is capable of instantiating that object is usually found in HEKY_CLASSES_ROOT\CLSID in the registry. To discuss this further would be to explain a lot about COM in Windows. But the error indicates that the COM guid is not present in the registry.

我不知道很多关于什么PackAndGo DLL是（欧特克成分），但我怀疑你只需要安装的组件或软件包它来通过指定安装有该DLL和相应的COM你想运行在您的code在您的计算机上的注册表项。 （即去运行setup.exe本产品）。

I don't much about what the PackAndGo DLL is (an Autodesk component), but I suspect you simply need to "install" that component or the software package it came with through the designated installer to have that DLL and appropriate COM registry keys on your computer you are trying to run your code on. (i.e. go run setup.exe for this product).

在换句话说，我认为你需要这台计算机上安装打包，而不是仅仅将DLL复制到目标机器。

In other words, I think you need to install "Pack and Go" on this computer instead of just copying the DLL to the target machine.

此外，还要确保你决定建立自己的code适合作为32位与64位取决于其建立包风味（32位或64位），然后转到你安装。

Also, make sure you decide to build your code appropriate as 32-bit vs. 64-bit depending on the which build flavor (32 or 64 bit) of Pack And Go you install.
