Update Installed Application
I have a VB.net Windows application (Visual Studio 2003) that I have updated. The application has been previously packaged and distributed to users. Is there a way to create an update, without generating a full install? Can anyone assist with this?
Use the same installation project for new application version. When it is installed on computer which already has previous version, it shows dialog with Upgrade option. This is standard behavour of every installation package.

The project solution already has an install project, as you already know. Do I need to create a new install project, or can I rebuild the current install project. Will the changes that I have made take effect? Then you are saying, if what i just said is successful, when i install to a machine that already has the application loaded it will prompt me to upgrade or update?

When i rebuilt the installation package and installed it on a machine with the previous version of the application, I received an error stating that there was a previous version installed. And I was not prompted to update. Why do you think it did this?
you need to flip the boolean that says allow for update.
its in the setup projects properties.

I don't see allow for update. Would it be remove previous versions?
Just replace the .dll in the application folder will do. If you upgrade to VS2005, try ClickOnce deployment.

What do you mean by "Just replace the .dll in the application folder will do."? Thanks.
If you update a component then .dll will do. If is an application then the .exe file.
