Remove SwSetup?

Be more explicit, what are you testing?
What is the exact problem?

I installed Divx Plus 8
I wanted to uninstall it, but it crashed and the uninstallation did not complete.
So I manually removed it, in a rough way.

I tried to install it again, it told me that the Codec and Player are already installed, but they are not present anymore. I tried CCleaner, Revo Uninstaller, no way, it still detects it as installed.

When I try to uninstall, I get this:

And this "offline installer" does nothing for me, just prompts for reinstallation.
