To remove SMEX manually:

1. Stop the following ScanMail-related services:
   • ScanMail for Microsoft Exchange Master Service
   • ScanMail for Microsoft Exchange Remote Configuration Server
   • ScanMail for Microsoft Exchange System Watcher
   • Microsoft Exchange Transport Service
2. Remove the ScanMail transport agent from Exchange 2007, 2010 or 2013.

   2. Type "Y".
   3. Execute the command "get-transportagent" to make sure that the ScanMail transport agent has been removed.
3. Delete the following registry keys:
    

   Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.

   Product registry keys:

   • HKLM\SOFTWARE\TrendMicro\ScanMail for Exchange
   • HKLM\SOFTWARE\Wow6432Node\TrendMicro\ScanMail for Exchange (This key only exists in 64-bit environments.)
   • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\D8512B02C8BA2364BBA61EFFA1DACD31 (EUQ)
   • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\F79BAC82EE02C8A4CB43EE3AB234B806 (SMEX)

   SMEX performance count register key:

   • HKLM\SYSTEM\CurrentControlSet\Services\Perf_Smex11PerfMonMgr

   Service registry keys:

   • HKLM\SYSTEM\CurrentControlSet\Services\ScanMail_Master

   • HKLM\SYSTEM\CurrentControlSet\Services\Eventlog\Application\Trend Micro ScanMail for Microsoft Exchange

   Registry key used during installation:

   • HKLM\SOFTWARE\TrendMicro\TEMP-RIFSTATUS\
    

   Use the search tool to look for registry keys with the value, "4FECAAEDA6A1D174B90DD4B342CE2327". Remove those keys with this value. When using the search tool, make sure that you select “Values” and “Match whole string only”.

6. Delete all files and subfolders in the folder where SMEX was installed.

   For example: C:\Program Files\Trend Micro\SMEX\

2. Ensure that the latest Microsoft Windows and Exchange Service Packs are applied.
3. Check and ensure that Windows TEMP directory are cleared.
4. Run the SMEX setup.

If the above steps do not resolve the issue that you encountered, do the following:

   RIFRemoteInstallAgent.exe	%windir%\temp\SMEX_RIFRemoteInstallAgent.log
   Msiexec.exe	SMEX program directory\Debug\Msiexec.log SMEX program directory\Debug\SMEX_Msi*.log
   InstSetupHelper.exe	SMEX program directory\Debug\SMEX_SetupHelper.log

2. Compress the files using WinZip and apply the password, "trend".
3. Send the files to Trend Micro Technical Support.
