How can i install wkhtmltopdf in civicrm and set the path to the exe. I am using Civicrm with Wordpress. Any help will be appreciated.
Download the compiled binaries for your system from http://wkhtmltopdf.org/downloads.html to your server and extract to somewhere convenient. The files need to be readable by the account running the webserver. Then go to Administer >> System Settings >> Misc and enter the path to the wkhtmltopdf.
I came across that by googling wkhtmltopdf civicrm by the way ;)
