[stunnel-users] Help installing stunnel 5.72 as service in windows 10

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 -William Wood
