Apparently to get stunnel to work, I have to install it as a service in Windows.  In order to do this, I fire up a powershell, change directories to the stunnel\bin\, and run the command:
.\stunnel -install

This results in the error message:
OpenSCManager: error 5: Access is denied
Not sure what to do, as I am running as an administrator
Any help would be appreciated
Thanks
