Software Download questions

I have been using the software on my desktop (appliance free) for a few years, but now need to install on my laptop as well for a big project in which I will be working away from my desk in order to meet deadlines. I have previously used the appliance on this laptop, but it has been a while. The first message that I received was that I would need to uninstall the old version, which I did. Then, upon install, got message asking about whether I wanted to copy info over from appliance. I do not, since I have not used the appliance in several years. However, I now just get an error trying to open and it tells me to attach appliance. What am I doing wrong? Thanks!
