System.IO.FileNotFoundException Reference not found on when run on users computer

Question

I am making a program in C# with Visual Studio Express 2013. I am using Ionic.zip (dotnetzip). When i run it from the .../bin/release directory or from Visual studio, it runs perfectly fine. when the end user has it on their computers, or I run it from another location, when it tries to perform an action using ionic.zip, it crashes with the following exception

System.IO.FileNotFoundException: Could not load file or assembly 'Ionic.Zip, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c' or one of its dependencies. The system cannot find the file specified.
File name: 'Ionic.Zip, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c'

I have absolutely no idea how to fix this, and have been researching for the last 3 days how to with no success. Any help will be appreciated.

Thanks, James

CHeck dependencies - either directly, or possibly a not installed framework reference. If the assemblz is in the search paths if should be found.

First include that file in your resources after that in its properties:

Select Build Action -> Content
Copy to Output Directory -> Copy if newer

enter image description here

I am attaching a picture. Now you can access its correct path as follows:

System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\Resources\\yourfile.exe";

Except that the folder a program starts in is automatically searched. – TomTom Jun 07 '14 at 13:59

You need to have an installer or script copy the DLL to the executing directory(where the executable is) or into the computers PATH.

Thanks. This is perfect. I would have assumed that referenced dll's get packaged into the exe file though :/ – therimmer96 Jun 07 '14 at 14:16
