Fedena PDF Settings :
PDF Reports in Fedena are generated using wkhtmltopdf. By default, we have set it to i386. If you are using AMD64, open file config/initializers/wicked_pdf.rb and change "i386" to "amd64"
You can download the wkhtmltopdf binaries from Google Code. After the file is downloaded, update the "exe_path" in config/initializers/wicked_pdf.rb with the Path to binary.
