Most likely you have a problem

1. Install prerequisites
2. Install application
3. Set permissions etc.
4. Update deployment manifest to reflect file location changes

You should check out this deployment paper:

Deploying Visual Studio 2005 Tools for Office Second Edition Solutions Using Windows Installer

Also, make sure that your assemblyCodeGroupName value has not spaces. It can be done, but it does introduce issues.
