Error 47 is an invalid record declaration. In plain english this just means the fields in the alarms file are different to the fields the program is expecting.
To install KA on another computer is really easy.
You just copy everything in the KA folder from the old computer to the new one.
Maybe the files are not copying across because they are use.
I suggest making doubly sure that kirbyalarmpro.exe is not running (use windows take manager if you have to).
Then copy the entire KA folder from the old computer to the new one.
If you get really stuck then let me know and we could arrange a suitable time to remotely connect to your computer and fix it for you.
