Unfortunately, I don't have that information right now but I hope Shane can explain more. However, you can use
Revo Uninstaller to help get rid of left over files, reg keys, etc....
Thanks Josh,
We can wait...
Re: Revo

Current version is 1.7
I used previous version(s) of it "against Vengine" as well in the past.
Revo actually is not bad SW but it cannot do everything.
The new version did better job though. For example, it removed
Esigil from registry... couldn't do it in the past when I was fighting Vengine 2.7.0.1.
At the same time there are other leftovers. I attached text file with some comments if anybody interested
The final note would be that eventually I removed all those leftovers.
But it turned to be still not enough. Reinstalling 2.7.0.2 after all that cleansing failed to show borders again in IE7 and Firefox 2.xxx.16.
... Uninstalled ... waiting for the new one to try
Cheers
