I bought a track IR device delivered with software 4.1.035 a few months ago.
My computer was unable to read the install CD. I dowloaded the sotfware on naturalpoint website and managed to make the Track IR work properly.
A fews weeks ago, I had a severe failure of my computer. I had to change my CD/DVD reader and to completely reinstall windows XP (lost all my data !)

I've just tried to use the CD again to reinstall the Track IR. The Install process starts but a mesaage with "Error number : 0x80040707" appears. The process goes on until it reaches a window where I have to select the component I want to install. This window is empty and I have to give up the install.
The same thing occurs with a sofware dowloaded from the website.
Thanks for any help.
