问语音云库调用失败？

我开发环境OK，有一些WINDOWS7电脑上，调用 m_voiceengine = GCloudVoice.GetEngine(); 的时候会出现报错

Description: The process was terminated due to an unhandled exception.

Exception Info: System.DllNotFoundException

Stack:

at gcloud_voice.GCloudVoiceEngine.GCloudVoice_CreateInstance()

at gcloud_voice.GCloudVoiceEngine..ctor()

at gcloud_voice.GCloudVoice.GetEngine()

我的GCloudVoice.dll文件放在当前目录下，有的电脑会出现这个问题，有的不会

还有我是调X86的库的
