Hey @guiltdriver,

Thanks for using the dev forum!

You are trying to use the C# wrapper correct? If so, did you follow the steps here: [https://marketplace.zoom.us/docs/sdk/native-sdks/windows/c-sharp-wrapper](https://marketplace.zoom.us/docs/sdk/native-sdks/windows/c-sharp-wrapper)

Thanks!  
Michael

I think the use is correct, most our meeting is work fluency,but if we don’t install vc++ redistributable package, it can’t join meeting

Hey @guiltdriver,

I believe this is just because the SDK is technically capable of running without the use of Visual Studio. Is there an issue with using the vc++ redistributable package in your environment?

Thanks!  
Michael
