While installing System Mechanic I receive the message, "You must first uninstall any other antivirus or firewall software before you can install System Mechanic."

This article applies to:
  • System Mechanic 8 Professional
  • System Mechanic 9 PC TotalCare
  • System Mechanic 9 Professional

While installing System Mechanic you may encounter the following message:

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

This indicates that System Mechanic Professional has detected third party antivirus or firewall 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 or firewall software installed and you believe you have received this message in error, the following process will allow you to bypass this detection screen.

Windows 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 SystemMechanicPro.exe installation file.

"C:\Users\User\AppData\Local\Temp\iolowupd\SystemMechanicPro.exe" /skipavfwcheck

If you saved the SystemMechanicPro.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 SystemMechanicPro.exe and use that file path.

Example: "C:\Documents and Settings\User\Desktop\SystemMechanicPro.exe" /skipavfwcheck would run the System Mechanic Professional setup file from your desktop if you had saved it there.

All Other Windows Users
Click Start>Run and enter the command below, including quotes, into the Open: text field. This quoted portion of the command includes the full default download path and folder location to the SystemMechanicPro.exe installation file.

"C:\Documents and Settings\User\Local Settings\Temp\iolowupd\SystemMechanicPro.exe” /skipavfwcheck

If you saved the SystemMechanicPro.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 SystemMechanicPro.exe and use that file path.

Example: "C:\Documents and Settings\User\Desktop\SystemMechanicPro.exe" /skipavfwcheck would run the System Mechanic Professional setup file from your desktop if you had saved it there.


System Mechanic 9 Professional Users
System Mechanic 9 Professional does not include a Firewall component.  For this reason it is unnecessary to uninstall your current firewall solution before installation. Any other antivirus or antispyware software must still be uninstalled before installation if you wish to install the System Shield AntiVirus & AntiSpyware component.


System Mechanic PC TotalCare Users
The instructions above also apply to users of System Mechanic PC TotalCare with one exception. The file name "SystemMechanicPro.exe" must be replaced with the proper System Mechanic PC TotalCare file name, "SystemMechanicPCTC.exe".
