Hi there and welcome
You will need to reinstall it if it is no longer on your mac. Use the disk it came on, put it into the Mac and run the installation. This will then return it to your Mac so that it can be used again.
Let me know the results please.
how then did you initially installed it when getting the Camera?
This is the other way it can be received.
What you need to do is download and install it again and you can do so via my link below
Make sure to download the version you will provided initially from Leica, and once downloaded, run the file to complete the installation
Let me know the results please,
yes of course you need the code which is what you used when you initially installed it. You were provided a code to enter, and it is this code you need to use. We cannot send codes here.
