Hello abhi30shek,
as mentioned in a previous message you will not be able to install SeoToaster CMS if for some reason this file is missing.
The Application.ini file is created automatically during SeoToaster install, we invite you again to start from scratch with our step by step installation of our CMS -
http://www.seotoaster.com/installation.html .
Once install is complete, you should find the file application.ini in the directory seotoaster_core/application/configs/
Thanks for using SeoToaster,
SeoToaster Support
