Hi all,
I found a solution for this issue. Don't go for the install folder in the Plesk. First install this app in your local system (using xampp) and export the .sql file using php my admin. After that upload all the files to the IIS server and go to the php myadmin area. Just import the .sql file to the server. Finished..... Cheers!!!!!
If any one having doubts feel free to contact me....
