Error when Uninstalling Overture: Haptx

[captainvic]

I am trying to uninstall Penumbra: Overture Haptx Edition and I get an error:

Error Code: -5006 : 0x80070002
Error Information:
>SetupNew\setup.cpp (615)
PAPPenumbra: Overture - HaptX Edition
PVENDOR:Frictional Games (##ID_STRING6##)
PGUID:EFE57636-9250-4965-8610-00532DCF7AB2
$14.0.0.162
@Windows XP Service Pack 2 (2600) IE 7.0.6000.16764

After this, I get a windows error box saying that it may not have uninstalled correctly. It never is removed from my programs list, and is apparently still installed. I can uninstall over and over again with no apparent effect. I have software that's literally "stuck" on my system now.

System specs:
Windows Vista Ultimate 32
AMD Athlon 64 X2 Dual Core 4600+
3gb Ram
Geforce 8800 GTX

I was trying to reinstall in the hope that it might correct the other issue I was having. This is turning into a really big mess...

Does anyone have some advice for me?
