You should add the following telerik assemblies to your setup project, for deployment:
- TelerikCommon.dll - this assembly contains general routines required by all controls
- Telerik.WinControls.dll - this assembly contains base the Telerik Presentation Framework (TPF) classes and routines
- Telerik.WinControls.UI.dll - holds all telerik UI controls.
For deployment on another computer, telerik assemblies should be either in the same folder, as the application executable file itself, or in the GAC.
I hope this information would help you with this issue.
All the best,
