Since you say you're running Win10 the easiest thing to do is to right-click on the Start button and select 'File Explorer', when that opens go to the address bar and click in it to highlight whatever is there (mine says 'Quick access'), then type shell:startup, this will open your startup folder. In the startup folder right-click in an empty area then select 'New > shortcut'; in the 'Create Shortcut' window that opens click 'Browse' and navigate to your Cumulus folder (mine is 'This PC > Local Disk (C:) > Cumulus') and select the Cumulus application file (it will have the Cumulus logo for an icon) and click 'OK'. When you're back at the 'Create Shortcut' window you will see the path for the application file, click on 'Next' and then if you're happy with the default name it assigns (should be 'cumulus') click 'OK'. This will add a shortcut for Cumulus in the startup folder and whenever your computer reboots Cumulus will start along with all the other programs like your AV, firewall, etc.
Yup. That works! Thanks.
But I did notice under Station Settings:Program Settings I had to have the following checked and unchecked:
Uncheck "Confirm Shutdown"
Uncheck "Close on Suspend"
Uncheck "Stop 2nd instance"
Check "Restart if unplugged"
Check "Restart if data stops"
I don't remember which one, but one extra was checked and when I minimized the program into the Task Bar, the program Icon showed there, but Cumulus would not re-open unless I rebooted the computer.
But all is well now and it works as intended.
