**Description**  
I’m using the C# module in my code and today after weeks of running my Zoom client without issue, I started getting SDKERR\_MODULE\_LOAD\_FAILED on initialization.

I rolled back my changes to a version that was previously working and I was still getting the error.  
I confirmed the DLLs were being copied with the EXE and I still get the error.  
I reset my SDK key and I still get the error.

Randomly, I tried removing `enable_log` from the `ZOOM_SDK_DOTNET_WRAP.InitParam` and it started loading again. When I tried adding that line back, it still was loading.

I started coding again and then suddenly I started getting SDKERR\_MODULE\_LOAD\_FAILED again, though I was adding to code not related to the Zoom SDK.

I would like to get some advice on what to do in these situations. Does the SDK Initialize procedure connect to a service that validates the SDK key, and if that fails then potentially the modules won’t load?

How can I get more details about SDKERR\_MODULE\_LOAD\_FAILED and what went wrong? Is there a way to see which module didn’t load?

Is there any reason for the temperamental nature of the SDK that I’ve described above?

**Which Windows Client SDK version?**  
5.5.12509.0330  
Assembly zoom\_sdk\_dotnet\_wrap, Version=1.0.7575.37543

**Device (please complete the following information):**

- Windows 10

I fixed this. The issue seems to be adding my “Util” project (a library with extra C# specific utility functions in it) to the project. It may have been colliding with the SDKs own “util.dll” library and causing that module not to load.

I renamed my project “Utilities” and things seem to be working now.
