Hi, Thanks for the reply.
I installed php in c:\php\php7.1.11
Edited all the settings(in php.ini file).
Created a folder named App in D drive and unzipped moodle there. I.e. D:\App\Moodle.
Now I configured IIS and added a application pool under default website named moodle with physical address as D:\App\moodle.
Now when I type http://localhost/moodle the moodle installation page shows up.
Now once I select language and press next I am getting this HTTP Error 405.0 - Method not allowed error. How do I proceed?
