This article details the troubleshooting steps in fixing installation/upgrade issues of the SA in WFBS. 


Check and remove previously installed Trend Micro products such as Titanium, Trend Micro Internet Security (TIS), Worry-Free Business Security (WFBS) client, OfficeScan client, and other Trend Micro products.

For existing WFBS client, just click Update Now from the main console. Do not try to install.

Check and remove third-party antivirus products currently installed. To know which products to uninstall, refer to this article: Antivirus software that Worry-Free Business Security (WFBS) can detect and uninstall

To manually remove the third-party software, contact their technical support for help.

Check if UAC is turned on. If it is enabled, disable the UAC before installing the SA, and then enabled it after SA has been installed. This allows you to identify if UAC is preventing you to install the program. For more information on how to disable and enable UAC, refer to this article: Turn User Account Control on or off

For remote installation, Trend Micro recommends that you disable the UAC.

Identify the installation method you are using. Choose another installation method for the SA if the first method you used failed. For more information about different methods of installation, refer to this article: Different installation methods for the Worry-Free Business Security (WFBS) Security Agent or Client/Server Security Agent

Check if you get an error code during installation. Refer to this article for solutions corresponding to error codes: Worry-Free Business Security (WFBS) installation and upgrade errors
Use the SA uninstall tool to manually remove components. Contact Trend Micro Technical Support to get assistance on how to get the Uninstall Tool.

If the installation still fails, collect the following and send it to Trend Micro Technical Support:%WINDIR%\Temp\WFBS_Debug folder for all types of installation/upgrade methods

  • ofcdebug.log from the Security Server for remote installation method
  • ..\CSA\Temp\upgrade*.log for issues encountered when upgrading from WFBS 5.x/6.x
  • Debug logs using the Case Diagnostic Tool (CDT). If you need more help with using CDT, refer to this article: Using the Case Diagnostic Tool (CDT)
There is no need to enable debug.
