This is because some anti-virus software installed will lead to an increase in the security level of the system and prevent programs from running automatically, including the installation program of KBao. Please temporarily turn off the antivirus software, click the Auto Play button in the control panel, select the "Use Auto Play for all media and devices" option in the top option, and turn on the auto play function, and KBao can be installed normally.

Or change the automatic play function of the system by manual setting. The method is as follows: Click Run in the start menu, type gpedit.msc, open Group Policy, expand Computer Configuration, expand Management Templates, select System, double-click the function of turning off autoplay on the right, and select Not Configured or Disabled. If it can't be played automatically, you can do the same operation as above in "User Configuration" below.
