Hi...
Unfortunately, that didn't give me as much as I was hoping for or much to work with. The site was for Windows XP, not Vista.
Well, to the extent of what I know, we have two choices...
1. You can uninstall the upgrade if it gives you that option, it may or may not. I don't know what kind of consequenes, if any, that will have. If it is successful, it should make the error message go away, I would think. Proceed with caution and at your own risk.
2. If the uninstall option is unavailable or things get botched from something unforseen from uninstalling the update, you can download the latest driver and Catalyst package for your card here...
http://ati.amd.com/support/driver.htmlI can give you a more precise link if you can tell me if your system is 32 or 64 bit. If 32 bit Vista....
http://game.amd.com/us-en/drivers_catalyst.aspx?p=vista32/integrated-vista32If you go this route, I would advise that you completely uninstall the entire previous graphics driver and Catalyst software before installing the new one.
Also, The update in question was "optional." My personal opinion is that these are to be installed only as needed, they are not installed automatically by default in Vista.
Hope this helps...
Best Regards...
