Problem installing Titanium

[pokishi]

Hello everyone, I've had to purchase a new comp, old one was on it's last legs. Anyways, during process of installing Titanium I get an error, D:\Data2.cab something along the lines of redundancy error. I remember having a similar issue installing on my old comp but can't remember what I was told to fix it. Any help would be greatly appreciated.
