Some customers might see the dialog window below when attempting to install System Mechanic, prompting to uninstall SCU (iolo's System Checkup application) and simply means it needs to be uninstalled before System Mechanic can be properly installed. 




  1. To uninstall iolo System Checkup, please navigate to the Windows Control Panel, select Programs and Features.
     
  2. When the panel appears, select System Checkup and then at the top of the panel click on Uninstall.
