Thank you very much for your answer. This is a really useful technique. Regular expressions will never cease to amaze me.

This leaves just the question of checking just the required few applications. But I think I'll do it by pushing "Name: $1 Version $2" onto a separate list and then, I'll do something along the lines of: 

foreach (@cleanlist) {
    if (/Adobe Reader.+Version\s+(.+)/) {
        $gathered_data{'AReaderVer'}=$1;
    }
}

Maybe it's not the best way, but I think it should work. Thank you very much for your help.
