I'm asked to enter a variable out of the four on offer. By trial and error I found that 'ENVIRONMENT variables' has the option of Program Files where Avast is located. I'm able to edit that into C:\Program Files\Avast Software\Avast\ - then there are many EXEs to choose from. I do not want to LAUNCH Avast, but want to access the context menu of the systray icon - which EXE to choose ? Clicking AvastUI.exe opens the Avast Free Antivirus which MIGHT lead to the choice I want, but
MOVE MOUSE TO TRAY ICON Icon="C:\\Program Files\\Avast Software\\Avast\\AvastUI.exe
MOUSE LEFT CLICK
does not open that window.
When I click on BROWSE, I get what I think are Notification options, rather than a list of the icons in the systray.
