ADB server didn't ACK ，genymotion启动程序失败

Question

[2019-01-27 19:44:22 - adb] ADB server didn't ACK

[2019-01-27 19:44:22 - adb] * failed to start daemon *

[2019-01-27 19:44:22 - ddms] 'G:\BaiduNetdiskDownload\adt-bundle-windows-x86-20140702\sdk\platform-tools\adb.exe,start-server' failed -- run manually if necessary

这是什么原因，怎么修改呢？

一会儿提示源码有错误，一会儿又是adb服务didn't Ack。重启几次都没用
