To resolve the issue:
- Take a snapshot first or back up the important files of your Apex One server.
For more information, refer to the following KB article: Files to back up before upgrading, migrating, or uninstalling the Apex One server.
- Copy CCSF_WIN32.zip and CCSF_X64.zip from the paths above to \Trend Micro\Apex One\PCCSRV\Admin\Utility\Touch.
If you noticed that the packages on the Apex One server include an old Tmumh.sys version, please contact Trend Micro Technical Support.
- Open a command prompt and type TmTouch.exe CCSF_WIN32.zip. It will change the timestamp of the package.
It is possible that the timestamp cannot be modified if the command is run from a folder in Program Files. If that is the case, copy the TmTouch from Admin\Utility\Touch and the two packages from C:\Temp and run the same commands.
- Type TmTouch.exe CCSF_X64.zip.
- Copy both files to their original directory:
- PCCSRV\Pccnt\Common\CCSF_WIN32.zip
- PCCSRV\Pccnt\Win64\X64\CCSF_X64.zip
- Wait until the following files have been updated:
- {OfficeScan Server}\PCCSRV\Download\hotfixNT.txt
- {OfficeScan Server}\PCCSRV\Download\hotfixNT_X64.txt
- Open the files with Text Editor and search for “CCSF_”. You should be able to get the following lines:
- /officescan/hotfix_pccnt/Common/CCSF_WIN32.zip=xxxxxxx (Timestamp)
- /officescan/hotfix_pccnt/Common/CCSF_WIN64.zip= xxxxxxx (Timestamp)
The timestamp should be updated. If not, please restart Apex One Server Master Service.
- Perform Update Now on the agent.
- Verify that the agent will update the tmumh.sys to the right version under C:\Windows\System32\drivers.
