DO NOT UPGRADE STUNNEL until you have been contacted by Vital Soft or Fiserv.

Prepare for Stunnel Upgrade

  • Please note that installation does require a reboot of your PC / workstation.
  • Save copies of the following 3 files - you will need them later in the upgrade process.
C:\Program Files\stunnel\certs.pem
C:\Program Files\stunnel\stunnel.pem
C:\Program Files\stunnel\stunnel.conf
  • Download the latest version of stunnel here.

Uninstall the Previous Version of Stunnel

  • Stop the Stunnel service
Run the Windows Services program, locate the stunnel service and click Stop.
  • Uninstall the currently installed version (5.01) of stunnel by running the following program.
C:\Program Files\stunnel\uninstall.exe
  • Verify that the C:\Program Files\stunnel directory was removed. If it remains, use File Manager to delete it.

Install Stunnel

  • Install the most recent version of stunnel (5.75 in June 2025.)
    • Choose the options that are appropriate for your organization.
    • By default, stunnel will be installed in C:\Program Files (x86)\
    • During installation you will be asked questions to create a default certificate. This certificate will not be used, so you can enter whatever values you choose or just press Enter on all of the prompts.
    • Do NOT run stunnel at the end of installation.

Complete the Installation

  • Copy the three saved files from step 1 (certs.pem, stunnel.pem and stunnel.conf) into the following directory:
C:\Program Files (x86)\stunnel\conf
  • Install the stunnel service using Powershell. If you installed stunnel for all users on the computer, you may need to run Powershell as the Administrator.
  • When Windows Powershell is running, enter the following commands:
cd C:\Program Files (x86)\stunnel\bin
./stunnel -uninstall
./stunnel -install
  • Reboot your PC.

Verifying the Installation

  • Run Windows Services and verify that the stunnel service is running. The service is now called "Stunnel TLS Wrapper".
  • If the service is running, launch Visimage3 and test that you are able to successfully start server.
