Uninstall DLL

Hi,

I accidentally created a deployment of a dll of some some support project rather than an exe for the primary project. And installed it. Now, I cannot install the the new msi, or figure out how to uninstall the dll.

The dll does not show up in the program manager. I tried upping the rev in the deployment project as work-around.

Does anyone know how to uninstall a dll?

A command line install with these options...
msiexec /i MyProject.msi /l*vx iLog.txt
... gives these error messages at the end, which basically means I have to uninstall the old version:
