I ran into the same problem in an application I was scripting. I don't have
a solution when some version of the application is not already running, but
this will work when it is:
tell application "Finder"
-- beware of the chevrons around "class psn "
set theProcess to (first process whose creator type is "FTCh") as +class
psn ;
end tell
using terms from application "Fetch 3.0.3"
tell theProcess
-- do something cool
end tell
end using terms from
Good Luck,
