Before rolling back the DCE and DCT, copy the following files to the pccsrv\admin folder:

  • For DCE, copy the previous version of tsc.exe and tsc64.exe.
  • For DCT, copy the previous version of tsc.ptn.

To manually roll back the DCE and DCT:

  1. Compress the previous version of TSC.exe or TSC64.exe into a zip file. For example, dce-exe-mssign-v62-1016.zip or dce-exe-mssign-32x64-v62-1016.zip.
  2. Copy the zip file to \PCCSRV\Download\Engine.
  3. Edit the pccsrv\download\server.ini file by modifying the file name, version, and file size.

    E.21080000=DCE_MSSIGN,engine/<file name>,<version>,<file size (bytes)>, 5.0.1000
    E.22000002=DCE_MSSIGN_32X64,engine/<file name>,<version>,<file size (bytes)>, ,5.3.1103

    Below is an example:

    E.21080000=DCE_MSSIGN,engine/dce-exe-mssign-v62-1016.zip,6.2.1016,376004, 5.0.1000
    E.22000002=DCE_MSSIGN_32X64,engine/dce-exe-mssign-32x64-v62-1016.zip,6.2.1016,1051808,5.3.1103

  4. Compress the previous version of TSC.ptn into tscptn.zip and copy it to \PCCSRV\Download\Pattern.
  5. Modify the pccsrv\download\server.ini file by adjusting the file name, version, and file size.

    P.800=pattern/<file name>,<version>,<file size(bytes)>

    Below is an example:

    P.800=pattern/tscptn.zip, 1258, 2125400
    P.800.MergeCountEx=0

  6. Change the following in the \PCCSRV\OfcScan.ini file:

    TSCEng_Version=the 32bit DCE version after rollback, e.g. 6.2.1016
    TSCEng_x64_Version=the 64bit DCE version after rollback
    TSCPtn_Version=the pattern version after rollback e.g. 1066

  7. Edit the [6107], [6108], and [6109] sections in the \PCCSRV\Private\component.ini file.
      • In [6107] section, enter the previous version of DCT. For example, "Version=1258 0 0"

        Version=<version> 0 0

      • In [6108] section, enter the previous version of DCE. For example, "Version=413696 1058 0".

        Version=<major version> <minor version> 0

      • In [6109] section, enter the previous version of DCE. For example, "Version=413696 1058 0".

        Version=<major version> <minor version> 0

     
    Use a calculator in programmer mode to get the major version. For example, if the previous version is 6.5, enter 65000 into HEX value and click Dec to get the result.
