Rocketmq4.2 version, how to install it in win7 environment

install the rocketmq4.2 version under the win7 environment. There is no installation tutorial for windows on the official website. According to the online tutorials, all the tutorials on the Internet are the old version, that is to say, starting mqnamesrv.exe, does not have this file at all, but only mqnamesrv, but starting this is wrong as shown in figure

.

ROKECT_HOME is also set up, but the error path is particularly strange. What is the correct way to install it?
