Hello
I am hoping someone has run into this issue and can help!!!
I am running into an issue and been struggling for a couple of days.
Hoping you can point me in the right direction 
I am developing on Windows Vista in Eclipse.
I am using Paperclip to add documents as attachments and create thumbnails. I have ImageMagick installed. The attachments are uploading no problem however when I try to create thumbnails I get the following error:
I have edited the command path in paperclip.rb to:
# :image_magick_path => nil,
:command_path => "C:\Program Files\ImageMagick-6.6.2- Q16",
I have also added the following line in environments/development.rb
Paperclip.options[:command_path] = "C:\Program Files \ImageMagick-6.6.2- Q16"
The model looks like:
class Collection < ActiveRecord::Base
belongs_to :user
validates_presence_of :name, :on => :create, :message => "can't be blank"
validates_presence_of :description, :on => :create, :message => "can't be blank"
# Paperclip has_attached_file :work,
:styles => { :thumb=> "100x100#",
:small => "150x150>",
:medium => "300x300>",
:large => "400x400>" }
validates_attachment_presence :work
validates_attachment_content_type :work,
:content_type => ['image/jpeg',
'image/pjpeg',
'image/jpg',
'image/png',
'image/gif',
'text/plain',
'application/ msword',
'application/ pdf',
'application/ octet-stream',
'audio/x-ms- wma',
'application/x- shockwave-flash',
'text/html',
'video/mp4',
'audio/mpeg']
end
The upload of documents works fine if I comment out the styles action.
When I try to create thumbnails with the styles action I get the followign browser error:
undefined method `exitstatus' for nil:NilClass
and I see the followign in the trace log:

I suspect that although I have defined the windows path to ImageMacick paperclip is still trying to look for the ImageMighc Identify binary in the unix directory structure : /usr/loacl/bin. Hence the error:
No such file or directory - /usr/local/bin/identify '-format'
Any suggestion will help greatly... I have been strugling with this for a few days now... Thanks
