To resolve this issue, launch the Clnpack.exe by right-clicking the file and selecting Run as administrator. The tool should be able to read the files that are in the PCCSRV folder.

If the issue persists, collect the following:

1. Open the OfficeScan server and go to ..\PCCSRV\Admin\Utility\ClientPackager\ClnExtor.ini file.
2. Under the [Common] section, look for the "DebugMode" parameter and set its value to "1".
3. Save and close the file.
4. Generate an EXE or MSI setup file.
5. Collect the debug log from C:\ClnPack.log. This is the debug log when creating package.
6. Before installing, enable the debug mode.
7. Manually create the ofcdebug.ini file on the target machine's system drive:
   1. Open a notepad and enter the following parameters:

      [debug]
      DebugLog=c:\ofcdebug.log
      DebugLevel=9

   2. Save the file as "ofcdebug.ini".

   For reference: Manually enabling debug mode on the server and clients in OfficeScan/Apex One

8. After performing the installation to reproduce the issue, collect these files from the client machine:
   • c:\ofcdebug.log
   • c:\clnextor.log
9. Collect the basic CDT logs.
   1. Download and run the CDT tool and enable the Basic debug logs only.
   2. Collect the CDT logs in a ZIP file format, along with the items mentioned above.
   3. Send the log files to Trend Micro Technical Support. This would generate a Service Request and notify Technical Support about an incoming customer generated ticket and process it accordingly.
