Problem with Ulead Software

Refer to my sig for pc specs.

I'd originally posted this in the windows general forum but apparently it was the wrong one so please forgive by double post.

I have a Ulead software I'm trying to install for my Vivitar ViviCam 6385u digital camera and it won't let me. When I try to, it tells me an earlier version is installed, remove it and try again. Well, it's been uninstalled. I noticed in the Add/Remove it's still there. When I click on it to remove it, it shows a pop up screen, Ulead Photo Explorer then in the screen >SetupDLL\SetupDLL.cpp(409) then under that $7.0.100.1342 then under that @Windows XP Service Pack 2 (2600)IE 7.0.6000.16640

Does anyone know what the heck that means and what can I do to fix this? I've checked regedit for any signs of it and can't find anything there. So I'm at a loss. There's other Ulead software which loaded with no problems.

Thanks for your help.
