Uninstall the Transflo DMS Workflow Engine and Components

If you ever need to reinstall the Transflo DMS Workflow Engine, use this article to learn how to uninstall all components properly for a successful fresh install. A reinstall of the Workflow engine components requires that the Workflow Engine and its components be uninstalled first.

When you uninstall the Workflow Engine and its components, it is essential that you perform the instructions in the sequence described in this topic. Do not attempt to delete Workflow Engine files directly. Removing these files directly may cause problems when you reinstall the Workflow Engine later.

Make sure of the following before uninstalling the Workflow Engine components:

  • TRANSFLO® Workflow Studio must not be on the server that houses the Workflow Engine during the removal of the Workflow Engine components.

  • If Workflow Studio is on this server, uninstall it first.

  • After the Workflow Engine components have been removed you can reinstall TRANSFLO® Workflow Studio.

To uninstall the TRANSFLO® Workflow Studio:

  1. Open the Add or Remove Programs window from the Windows® Control Panel.

  2. Select TIBCO Universal Installer (<path>). The path indicates where Workflow Studio was installed.

    Depending on the version of TRANSFLO® Workflow Studio installed on your computer the TIBCO Universal Installer entry may or may not be listed in the Windows® Control Panel. If not, disregard this step.

  3. Click Change/Remove and follow the uninstall instructions.

  4. Select TRANSFLO® Workflow Studio 2012 in the list and click Remove. Follow the uninstall instructions.

  5. Close the Add or Remove Programs and Windows® Control Panel windows.

  6. Backup your Workflow database schema and any other data related files. Configuration changes that were made prior to installation are not automatically removed during uninstall of the Workflow Engine. Any such changes must be changed back to their original values manually.

  7. If you are removing TRANSFLO® Workflow 2010 R1, uninstall TIBCO EMS and TIBCO Hawk from the Workflow Server using Windows® Add or Remove Programs.

    Skip this step if you are removing TRANSFLO® Workflow 2010 R2 or TRANSFLO® Workflow 2012.

  8. If TIBCO Rendezvous is installed or is showing in the Windows® Add or Remove Programs uninstall it.

  9. If you are removing TRANSFLO® Workflow 2010 R1, uninstall the TIBCOiProcess Web Services Plug-in from Windows® Add or Remove Programs.

    Skip this step if you are removing TRANSFLO® Workflow 2010 R2 or TRANSFLO® Workflow 2012.
