**Description**  
I have copied the sample code from “Initialize the SDK”, and it compiles without errors. When I run the code, the call to initialize the Video SDK always returns 1, which is supposedly the value of the error code “ZoomVideoSDKErrors\_Wrong\_Usage”:

`int returnVal = m_pVideoSDK->initialize(initParams); // Always returns 1`

**Which Windows Video SDK version?**  
zoom-video-sdk-windows-1.3.2

**Additional context**  
I am using the sample code copied straight from the Zoom Developer website ([Initialize the SDK](https://marketplace.zoom.us/docs/sdk/video/windows/essential/initialize/#initialize-the-sdk)), so I am surprised that it does not work as is. I suspect the code samples there are obsolete, and that some necessary steps are missing.

I am using the 32-bit (x86) Video SDK libraries (version 1.3.2), compiling and linking successfully under Qt 5.15.2 MinGW 32-bit.

Hi @drpclind ,

Can you please provide the full stack trace in text so that we can better assist?

Thanks,

Hello,

I have generated a stack trace at the point where the following code is called:

`int returnVal = m_pVideoSDK->initialize(initParams);`

My IDE does not trace into the initialize() function, probably because the library does not have debug information.

A couple years ago, when I was using an older version of the SDK (when JWT was being used for authorization), I had a [similar problem](https://devforum.zoom.us/t/error-13023-authret-keyorsecretwrong/37268/8) that was traced to a mismatch in the order of function entry points in the DLL. I think my linker was mixing up the entry points and calling the wrong function. I am wondering if a similar problem is happening this time? In the past, I think I fixed it by hacking the associated .h file to change the order of the function declarations.

Here is the stack trace. I will be happy to send you any further information that you may need.

Thanks

I was able to resolve the problem by switching from MinGW to MSVC. Disappointing, but manageable.
