Don't have the auto install enabled. Just choose the 'notify,but don'r install' option(custom). When you go to the dn/load site and it loads all the ones it 'thinks' you need. Click the plus next to the IE7 one(and any others you may want to cancel) and there should be a 'remove' button to click. Don't remember for sure,but there may be the option to 'never show again' there also...
