Deployment visio problem

Hi all

Hi. I am using Visio drawing in a application Visual studio .net 2005.


I build package in pakage & deployment of Visual Studio .net and include all dependencies. The problem is than when I run setup on client maching (than not have microsoft visio) it give me error message on that from where
visio control present and the error is Class not Register.

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

what would i do?

Is necesary that the client have MIcrosoft visio intalled?

I only want use visio sdk viewer 2003 on the client machine.
