Microsoft.Expression.Encoder.Utilities.dll is part of Expression Studio. If it isn't installed on the target machine it will not be found.

I don't know if these DLLs can be freely distributed, but you should find out before trying to distribute them with your application.

try to locate this dll-file on your machine, and distribute it with your executable to a pc that hasn't got expression installed.

when a program is about to use a dll, it looks in some predesignated places on the computer. one of the first places is in the folder the executable is executed in. one of the later places is probably c:\windows\system32

you have the filename though, so it shouldn't be that hard. unless microsoft has created some sort of mechanism stopping the distribution of the expression utilities.
