Baidu let most of the utilities install without incident. It popped up a red warning about three of them (this is not color-coding; all of Baidu's warnings are red). One warning said to disallow the action "if it is not an authorized operation." But how would the user know? Another said, "Only installation of security software or hardware should perform this operation," which suggests strongly that the user should choose to Reject the action. In all three cases, choosing Reject prevented correct installation and operation.
