Could not load file or assembly 'Aurigma.GraphicsMill' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Exception Details:

Tried as suggested by Graphicsmill frequent asked questions forums for Web Application

How to Resolve BadImageFormatException. (http://www.graphicsmill.com/docs/gm/frequently-asked-questions.htm)

Any other suggestions to make web-site run in my local-machine through visual studio 2013 is really helpful.

I found the answer, need to change to Relevant Application Pool.

Answer 2

There's a lot of information about this problem. Most of it is about a problem with 64-bit vs 32-bit. Well, my exact problem was I was using 64-bit Aurigma.GraphicsMill but my App pool (DefaultAppPool) had Enable 32-Bit Applications set to True which if you read the description on the bottom of the window says it makes your app run in 32-bit Mode. I was trying to run a 64-bit .dll from a 32-bit application.
