Is it possible to sense whether an application exists on any mounted volumes by giving its creator code?

#2

Using Akua:

try
    display dialog (path to creator "MSWD" as string)
on error
    display dialog "Can't find it"
end try

Thanks Marc, pleased to see vanilla solution. I first thought that the “Finder” takes this info from the desktop database, and again I thought that if I delete an application, it still would be reported if I don’t rebuild the desktop files. I tested and, no, it worked properly. What a sceptic man I am -:slight_smile:

Uing the Find document addition :
find application of creator “MSWD” if answer is {} then display dialog “Not found”

The Finder can find an application’s file by its creator code:

set theRslt to (display dialog "Please enter the creator code:" default answer "")
set theCreator to text returned of theRslt
tell application "Finder"
        try
                set theName to name of application file id theCreator
                display dialog "The application is " & theName buttons {"OK"} default button 1
        on error
                display dialog "There is no application for creator code "" & ¬
                        theCreator & """ buttons {"OK"} default button 1
        end try
end tell
