The ACU installation failed

Core Issue

Installation of the Aironet Client Utility (ACU) has failed.


If your attempt to install ACU fails, follow these steps:

  1. Close any Windows programs that are running.
  2. Select Start > Run, and enter the path to the installed ACU files (the default location is C:\Program Files\Cisco Aironet\setup.exe), and click OK. The Welcome screen for the Aironet Client Utility setup maintenance program appears.
  3. Select Repair and click Next. The Setup Complete screen appears.
  4. If your computer needs to be rebooted, select Yes, I want to restart my computer now or No, I will restart my computer later.
    Note: If you are prompted to reboot your computer, Cisco recommends that you select the Yes, I want to restart my computer now option.
  5. Click Finish. The repair is complete. All of the selections you made during the previous installation are maintained.
