1. Remove the OfficeScan website from IIS via IIS Manager.
2. Open a command prompt and navigate to the ..\PCCSRV folder.
3. Run these commands:

   Svrsvcsetup.exe -setvirdir
   Svrsvcsetup.exe -setprivilege
   Svrsvcsetup.exe -enablessl (This is optional if SSL is enabled.)

4. Log on to the OfficeScan management console.

Disregard this procedure if you are using Intrusion Defense Firewall (IDF) and Apache for web server to prevent OSCE Master Service from not being created.

1. Open the Registry Editor.
    

   Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
2. Go to [HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\OfficeScan], right-click on it, and then select Export to export the registry entry to TrendOfficeScan.reg.
   For 64-bit OfficeScan server, the registry is [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\OfficeScan].
3. Close the Registry Editor.
4. Open a command prompt and navigate to the ..\PCCSRV folder.
5. Go back to the command prompt and type the following:
    

   Compared to "-uninstall", using "-uninstall_regen" will not uninstall the Apache web server. This also prevents issues where Ofcservice.exe is not reinstalled. "-enablessl" is optional if SSL is enabled.

   Svrsvcsetup.exe -BackupAosReg
   Svrsvcsetup.exe -uninstall_regen
   Svrsvcsetup.exe -install
   Svrsvcsetup.exe -setprivilege
   Svrsvcsetup.exe -enablessl
   Svrsvcsetup.exe -RestoreAosReg

6. Restart the Officescan Plug-in Manager service.
7. Start the OfficeScan Master Service (if stopped).
