To deploy a Windows Forms application using Infragistics Controls, take these steps:
Copy your application to a folder on your client machine. 
Copy all Infragistics assemblies that you're using in your application into the 
same folder as the application's executable on the client machine. 
Copy infragistics.shared.dll and infragistics.win.dll into the same folder as 
the application's executable on the client machine. These files are typically located in an Infragistics 
folder in the C:\Program Files\Common Files folder of your development PC. 
An alternative is to use the VisualStudio.NET Setup Wizard, 
which automatically creates an installation package that will place the 
necessary files into the correct locations on the client computer.
