New Post: Running under IIS AppPool Identity?

Has anyone managed to get Magick.NET to run under an IIS AppPool Identity? I can't seem to figure out what permissions I need to set to allow this to work. If I run the site under a privileged user it will work so I know it's permissions of some description. I found that it needs to be able to write to the temp environment folder and have given that access but there m,ust be something else

The errors I get are:

• Failed to load embedded assembly: The type initializer for 'ImageMagick.MagickNET' threw an exception.
  

Inner exception:

• Magick: Error when saving the profile into a file '.' @ warning/opencl.c/autoSelectDevice/2303
  

Thanks in advance,

Chris
