If you already have a copy of the AT SERVER that is registered (ie has the AT SERVER DATABASE CONNECTIVITY enabled), then you can move the registration to a different PC using the "transfer ID CODE" feature
You can transfer it as many times as you like, and you don't need to get a fresh key code from Voltech each time.
The attached document explains how to do this.
This will disable the old copy, and enable your new copy.
If however, you have never purchased the DB CONNECTIVITY option, you will have to purchase a key code from us.
I hope this answers your question, please let us know how you get on, or if you need any more help
