I have a Radeon 9600 video card. I tried to update it by installing the Catalyst Software Suite. I tried to run the setup but every time I try I get an error message that just says 'Notify' and has an 'OK' button. So I click it then I get another that says 'data.size() != 3' with an OK button. Then after I click ok I get another one that says 'Setup failed to run installation: (0x80040707)'. Once I click ok the entire thing closes. If anybody would knows how to get this fixed that would be very helpful.

Funny you say that,

I had this EXACT problem when I installed the NVidia drivers on an old laptop to.

I just Right Clicked on My Computer > Properties > Hardware > Device Manager > Display Adapters > Right clicked on the yellow ! > Update drivers > Install from a list or specific location > found my driver and woila!

Worked like a charm.

Apparently that 0x80040707 install problem is generated by the Install Shield program within Windows.

I did all of that. Except that I cant find my driver. There are 3 different ATI manufacturers; ATI, ATI Technologies Inc, and ATI Technologies, Inc. There are Rage, 3D Rage, Mobility 128, Mach64, and ATI-264 models. Do you know which one I should pick?

Hello,

Go here then click on your operating system [e.g. Windows XP Pro] > Radeon > Radeon 9600 series

I downloaded the Catalyst Software Suite. Tried to install and got the same messages. I thought read somewhere that I need to uninstall my old driver. Even when I did that and tried to install it said there was new vga hardware found. Then I tried to follow the steps you said in your first reply but there wasn't a Display Driver in the device manager.
