Give this a go, @noisneil. Long-form and arrow-headed for readability.
It seems the trick is to select the row containing the checkbox before you click the checkbox...
tell application "System Events"
tell application process "Installer"
tell window 1
tell group 1
tell splitter group 1
tell group 1
tell scroll area 1
tell outline 1
repeat with eachRow in (get every row)
set cbName to name of checkbox 1 of eachRow
if cbName contains "AAX" or cbName contains "VST" then
select eachRow
tell checkbox 1 of eachRow
click
end tell
end if
end repeat
end tell
end tell
end tell
end tell
end tell
end tell
end tell
end tell
You can then create a "choice changes file" -- an XML file that the installer merges with the original to create an install solution it can then run.
That's as much of the theory as I know -- and I have never done this in practice! I'll dig further if the AS above isn't working, coz it's something I should learn about anyway...
More info available via the Terminal with man installer if you're interested.
You've only gone and nailed it! Thankyou so much!!! The only way it could be improved is if the list of strings to check for could be set as a KM variable and then iterated in the AS.
set inst to system attribute "KMINSTANCE"
tell application "Keyboard Maestro Engine"
set searchStrings to getvariable "Local_theSearchStrings" instance inst
end tell
tell application "System Events"
tell application process "Installer"
tell window 1
--activate
tell group 1
tell splitter group 1
tell group 1
tell scroll area 1
tell outline 1
repeat with eachRow in (get every row)
set cbName to name of checkbox 1 of eachRow
repeat with eachItem in (every paragraph of searchStrings)
if cbName contains eachItem then
select eachRow
tell checkbox 1 of eachRow
click
end tell
exit repeat
end if
end repeat
end repeat
end tell
end tell
end tell
end tell
end tell
end tell
end tell
end tell
