Old install of frameowork OK for new build of application ?

[StevenK]

We've previously developed an application (C#) for a customer using a previous release of Visual Studio 2002. In order for this application to run on their client machine we needed to install the .NET framework.
We've now changed our version of Visual Studio to the latest release, namely 2003.

My question is this :
Do we need to install a new version of the .NET framework on the client machine in order for the new build of the compiled appliction to work ? (obviously on opening the source code in more recent IDE updated files and the like).
Or can we get away with running the new build of the application on the client machine as is (with the .NET framework as was) ?

Any pointers would be appreciated.
Thanks in advance
Steve

Any deployed Setup projects will most likely not be functional as it will prompt you with "You have an older version of .net (1.0)" [or something], though theres a chance if you just run the Release executables on the client machine it may work.
