Rails and Paperclip Errno::EACCES Permission denied

I'm stuck with this for days. I keep getting this error trying to upload image:

Errno::EACCES in MyController#create

Permission denied - c:\"Program Files\ImageMagick-6.6.9-Q16"/convert "C:/Users/USER/AppData/Local/Temp/stream20110522-5332-1e34ydw.jpg[0]" -resize "848x608!" "C:/Users/USER/AppData/Local/Temp/stream20110522-5332-1e34ydw20110522-5332-z5iv1g" 2>NUL

when I copy this line above to the command line and run it, it works - no permission denied error. What should I do to allow ruby do it?

I'm running on:

Windows 7

WEBrick 1.3.1

ruby 1.9.2p180 (2011-02-18) [i386-mingw32]

rails (3.0.7)

Paperclip - I've tried versions 2.3.11, 2.3.4, and 2.3.6, and 2.3.10 but I still keep getting the same error.

I've googled a lot for a solution and aplied the tempfile fsync fix found on [http://thewebfellas.com/blog/2008/11/2/goodbye-attachment_fu-hello-paperclip][1]

and also the file.mv replacement with copy and delete, in tempfile, that looked like the solution, but that doesn't help. These fixes besides seems to be in the newer versions of paperclip by default.

Of course I restarted webrick allways I made any changes.

The console info by server, when this problem rises:

OK, I finally found a solution, it was kinda stupid:

I reinstalled the ImageMagick, and instead of using the default folder in Program Files, I picked folder C:\im, than I set the

Paperclip.options[:command_path] = "C:\\im" 

in development.rb and now it works perfectly, with and without the styles options.

Thanks to everyone who tried to help.
