Afer I call login, I fetch last error through GetZoomLastError() and get these error.
ErrorDescription=SDK internal error. You can retry this feature by restarting the program. If you still cannot solve the problem, please contact our support engineer.
and other last error, example:
description=The SDK can not find the corresponding zoom dll file, or the corresponding zoom dll file is incorrect, please check if the sdk package is correct.]||
description= Make sure the SDK service is already created and enabled before call this method.]|
But the sdk seams works well, even it has these error.
