I want to generate PDF from a html doc in a rails app. So I decided to use wicked\_pdf. But its not working. I tried to integrate it in an app, but it did not work. So I thought of trying to see if it works in the rails console then i will integrate it in the app.

Here's what I came across in the console

```
wp = WickedPdf.new
=> #<WickedPdf:0x4e7eea0 @exe_path="C:\\wkhtmltopdf\\wkhtmltopdf.exe">
HTML_DOCUMENT = "<html><body>Hello World</body></html>"
=> "<html><body>Hello World</body></html>"
pdf = wp.pdf_from_string HTML_DOCUMENT
"***************C:\\wkhtmltopdf\\wkhtmltopdf.exe  - - ***************"
NotImplementedError: fork() function is unimplemented on this machine
    from C:/Ruby/lib/ruby/1.8/open3.rb:57:in `fork'
    from C:/Ruby/lib/ruby/1.8/open3.rb:57:in `popen3'
    from C:/Users/raw/Desktop/html/scheduler/vendor/plugins/wicked_pdf/lib/wicked_pdf.rb:22:in `pdf_from_string'
    from (irb):3

```

**UPDATE:** I am using Windows7

I am not able to figure out where I am going wrong.

Please help.

Thanks in advance.
