If you already have the MSI proceed to step 4.

1. Remote into the trend server
2. Navigate to C:\Program Files (x86)\Trend Micro\OfficeScan\PCCSRV\Admin\Utility\ClientPackager and run ClnPack.exe
3. In the Client Packager, set the package type to MSI, make sure the scan method is set to Conventional, and choose the ellipses next to “Output file” choose a name and save location. Then click Create at the bottom.
4. Move the created MSI to the machine you’ll create the package on.
5. Create Install.bat with the code listed in Scripts.
6. Compile the MSI and install.bat into a zip file and upload into KACE
1. Installation Command is set to Configure Manually and set to look at Install.bat
2. Don't prepend msiexec.exe
3. Delete Downloaded Files

The install time for this was 2 minutes, tested and deployed on Win 7 Pro (32/64) and Win XP (32/64). This installed version 10.6.1062. A restart may be required, but does not force the user, instead just gives them reminders.

Create an install.bat to be used in the package with the MSI.

if exist "C:\Program Files\Trend Micro\OfficeScan Client\PccNTMon.exe" goto END
if exist "C:\Program Files(x86)\Trend Micro\OfficeScan Client\PccNTMon.exe" goto END

msiexec /i "TrendMicroOfficescan.msi" MSIFASTINSTALL=1 /qn /norestart RUNATONCE="yes"

:END

#Trend Uninstall
If (Test-Path "C:\Program Files (x86)\Trend Micro\OfficeScan Client\ntrmv.exe")
{
	Write-Host Uninstalling Trend Micro Office Scan... This will take time...
	Start-Process -FilePath "C:\Program Files (x86)\Trend Micro\OfficeScan Client\ntrmv.exe" -Args 'NOPASSWORD', 'SILENTUNINSTALL', '-s' -Wait -WindowStyle Hidden -ErrorAction SilentlyContinue
	Do
	{
		Write-Host Looping script until uninstall is complete...
		Start-Sleep 15
	}
	until (-not (Test-Path "C:\Program Files (x86)\Trend Micro\OfficeScan Client\ntrmv.exe"))
	Remove-Item "C:\Program Files (x86)\Trend Micro\OfficeScan Client\*" -Force -Recurse -ErrorAction SilentlyContinue
}

Another way:

1. On the OfficeScan-Server, you connect via UNC to  \\"OFFICESCAN-HOST"\ofcscan\Admin\Utility\ClientPackager    and run ClnPack.exe

2. Change Packet Type to MSI

3. At the bottom select the following Source file \\"OFFICESCAN-HOST"\ofcscan\ofcscan.ini

4. Select Output File into any path you want and click on "create" at the bottom to start the process to create a MSI-package of your TrendMicro installation.

5. Upload the MSI to KACE and select Installation command as standard. Add the parameters /i for verifying installation, /quiet for silent install and /norestart to force the client not to restart.
