Missing dll in Windows version

[neyon]

When uploading images via Paperclip on Ruby on Rails, I get this error during execution of a watermark processor:

Code: Select all

convert.exe: unable to open module file `C:\Program Files (x86)\ImageMagick-6.9.1-Q16\modules\coders\IM_MOD_RL_'C_.dll': No such file o
y @ warning/module.c/GetMagickModulePath/672.

I'm on Windows 8.1 64-bit and get the same dll missing error with the x64 version of IM.

Any clues? Thanks.
