Serial Port programming

ClickOnce Installs fail, "ADODB 7.0.3300 required"?

Today I used ClickOnce to publish a new version of my project. But it failed. The error says:

"Unable to install or run the application. The application requies the assembly ADODB 7.0.3300 to be installed in the Global Assembly Cache (GAC) first."

I tried to find the ADODB 7.0.3300. But no way I can find it. The only thing I added to project is Report Viewer. So I removed the reference to ReportViewer, and tried again. It worked. It seems the ReportViewer references this mysterious ADODB 7.0.3300.
