Error D:/wamp64 or PHP in PATH (no replies)

At the bottom of Wampmanager this error message shows "Error D:/wamp64 or PHP in PATH" and when click this message the details of this message is shown
"Sorry,

There is an error.

There is Wampserver path (D:/wamp64)
into Windows PATH environnement variable: (D:\wamp64\bin\php\php7.1.9)

It seems that a PHP installation is declared in the environment variable PATH
D:\wamp64\bin\php\php7.1.9

Wampserver does not use, modify or require the PATH environment variable.
Using a PATH on Wampserver or PHP version
is detrimental to the proper functioning of Wampserver.
"

I have checked my systems environment variables and found this line 'D:\wamp64\bin\php\php7.1.9' and after deleting this no error message shown in wampmanager. But problem is Im using PHP framework 'Laravel' for my project which requires PHP dependency manager 'Composer' and during installation of composer its mandatory to choose a command line php and when I choose php 7.1.9 it sets into my environment variable PATH. If i delete this PATH composer will not work. Now what should I do to resolve this issue.

Please help. Any ideas?
