There is a problem when I upgraded Media Expresso.

It came with PowerDVD 13 ultra upgrade and the problem is I tried to launch Media Expresso 6.7 and it wanted to uninstall the old version of media expresso and so it tried.

The problem is however, I do not believe it did a proper install or uninstall of media expresso.

I cannot find the uninstall in the Add Remove Programs in control panel.

I cannot run the installer anymore as it says an "error reading setup initialization file"

I have tried to download the installer again and it did not work.

It keeps detecting old version. If I would have known I would have manually uninstalled the old version. I thought I was getting an upgrade from 12 Ultra but I guess it was just a fresh install.

Is there a way to manually uninstall it through regedit, file deletion.
I don't know where all the keys are.
