Issue with running the samples

hi All,

i am facing an issue while Running the .net sample Projects with Visual studio 2010 (Windows 7 64 bit Operating System)

"Could not load file or assembly 'dotnet_emdq, Version=1.0.4496.42818, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format."

Thanks,
