This article describes the administrator procedure for manually uninstalling DPX in a Windows environment.



"Add remove programs" uninstalls the software partially. You can see registry entries corresponding to DPX software installation.

In this situation, follow the below steps to manually uninstall the product.



To uninstall DPX from Windows manually:

  • Ensure that you have a complete backup of the computer from where you are uninstalling DPX.
  • In the DPX command prompt, cd to the DPX tools directory.
  • Remove all installed services using the bexsvc tool as follows:

a. Enter the following command: bexsvc --h

b. Navigate to services, open the service properties, and review the service names to find
the service to remove. To remove the service, run the following command:
bexsvc --rem --name <Service Name>

c. Remove all services in this name that start with Catalogic Software DPX.

  • Delete DPX and BEX services under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.
  • Delete DPX and BEX reg structure HKEY_LOCAL_MACHINE\SOFTWARE\Syncsort.
  • If x64, delete reg structure HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432node\Syncsort.
  • Go to location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{71A27CDD-812A-11D0-BEC7-08002BE2092F}.
    Edit the UpperFilters string NOT to contain BexWinCj.

  • Go to location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{533C5B84-EC70-11D2-9505-00C04F79DEAF}.
    Edit the UpperFilters string NOT to contain BexWinCj.

  • Go to location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts and delete registry `String Value` that have data values pointing to SSPRODIR (you will see this issue mostly on Master Server installs).
  • From the %SystemRoot%/system32/drivers directory, remove the files BexWinCj.sys and BexWinCJFlt.sys.
  • Delete SSPRODIR. If that does not work due to files being open, reboot.
  • To remove the entry from Add/Remove programs, find the DPX installation in HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall and remove entries related to DPX.
  • Reboot the machine and run the installation.

    Warning: If you use Registry Editor incorrectly, you may cause serious problems that may require
    you to reinstall the operating system. Microsoft cannot guarantee that you can solve problems that
    result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
  • Reboot the computer.
