While installing System Shield AntiVirus and AntiSpyware I receive the message, "You must first uninstall any other antivirus software before you can install System Shield."

This article applies to:
  • System Shield 4

While installing System Shield AntiVirus and AntiSpyware you may encounter the following message:

"Installation Cannot Continue.
      You must first uninstall any other antivirus software before you can install System Shield."

This indicates that System Shield has detected third party antivirus software installed on your PC and installation has been halted due to possible conflicts. In most cases removing these third party programs from your PC will resolve the issue and allow you to continue installation. If you do not have antivirus software installed and you believe you have received this message in error, the following process will allow you to bypass this detection screen.

Windows 7/Vista Users
Click Start and enter the command below, including quotes, into the Start Search text field. This quoted portion of the command includes the full default download path and folder location to the SystemShield4.exe installation file.

"C:\Users\(User)\AppData\Local\Temp\iolowupd\SystemShield4.exe" /skipavfwcheck

If you saved the SystemShield4.exe installation file to a different location, please ensure you correct the file path location. If you are unsure where the file was saved, perform a file search for SystemShield4.exe and use that file path.
