Hi Melanie
1.You can have an interface on your current system
OR
2. You can share(MAP) the Drive that has your old registration system and your AC .
3 So when you remotely connect with your netbook to your computer which has the AC and your old system from anywhere,you will be able to see and use both systems
4. I am sure you are aware that the main computer you want to access that has your AC and your other progam has to be ON all the time.
