Unzip the file : apache-ant-1.10.3-bin.zip
Note this path. And go to Windows System variables and use new.
You can type the Variable name : ANT_HOME
Give your Ant software unzipped path, Variable value:
D:\Ant\apache-ant-1.10.3-bin\apache-ant-1.10.3\bin

Note: I gave my ANT path as example.

Goto System variables section and edit/add ANT_HOME variable and
give your current path:
D:\Ant\apache-ant-1.10.3-bin\apache-ant-1.10.3

And the variable can be named as %ANT_HOME%\bin

So you have updated the windows settings for ANT folder Location.

Now, open a fresh CMD window and check the ANT folder as below:
Microsoft Windows [Version 10.0.16299.431]
(c) 2017 Microsoft Corporation. All rights reserved.

C:\Users\Toshiba>echo %ANT_HOME%
D:\Ant\apache-ant-1.10.3-bin\apache-ant-1.10.3\bin

C:\Users\Toshiba>

How to cheeck your current ANT version?:
Now, In a fresh command window,
And apply as below:

C:\Users\Toshiba>echo %ANT_HOME%
D:\Ant\apache-ant-1.10.3-bin\apache-ant-1.10.3

C:\Users\Toshiba>ant -v
Apache Ant(TM) version 1.10.3 compiled on March 24 2018
Trying the default build file: build.xml
Buildfile: build.xml does not exist!
Build failed

C:\Users\Toshiba>

Now, it shows your ANT folder and its version also.
It means your ANT software can be used.
