A few items to hit:
- Your current license will likely support up to 2 computers. Only after that would you need to consider expanding.
- For prefs file I see 2 possible options
2a. Create a dummy laser to get LB started. Doesn’t matter what since you’ll soon be getting rid of it. Choose “Create manually” when asked. Once done, do a File->Import Prefs
2b. I think you may be able to navigate to the expected location of the prefs file before setting up LB and place the file there. Then start LB.
