Remove ATI 2010 when 2011 downloaded?

Thread needs solution

I downloaded ATI Home 2011 as an upgrade. On my Windows XP Control Panel "Add/Remove Programs" both ATI Home (2010?) and ATI Home 2011 are listed as programs on my computer. Should I delete the old ATI program?

I would recommend you uninstall both programs, use the cleanup utility and then reinstall 2011. This will help avoid driver issues.

Be sure to write down your key numbers before you unistall as you may need both to install the ati2011 upgrade. It won't ask for the old number if the older program is still present, but if it's uninstalled then it will ask for the older number besides asking for the new number.

I would also recommend that you a program like Revo Uninstaller after you Add/Remove programs just to be sure you removed everything
