In the SDK for macOS, it is relatively easy to run multiple instances of an SDK app from a single machine. I am not sure how to do this on Windows, is it possible without sandboxing multiple installs? If you just run the windows executable twice, you get SDK init error 14

Hey @liminal_andy,

Thanks for using the dev forum! It is nice to see you again.

We do not encourage this in the Windows SDK and we do not consider this feature supported, but you can run multiple instances by setting the sdkPathPostfix to a unique value per-instance [ZOOM Windows SDK: tagConfigurableOptions Struct Reference](https://marketplacefront.zoom.us/sdk/meeting/windows/structtag_configurable_options.html)

Thanks!  
Michael

Gotcha, thanks again Michael! Understood on the unsupported path I’m walking down:
