I have downloaded the logos 4 free software onto my computer. Since Logos is in version 4, do I need to get rid of logos 3 software desktop icon or should I wait to get rid of it when I get the full program?
Logos4 and Logos3 can reside on your computer together. In fact you can have them both open at the same time. You might want to wait before uninstalling Logos3 if you want to import your notes from Logos3 into Logos4.
EDIT: i would definitely wait on uninstalling Logos3 (Libronix).
i would not uninstall it as it will save you time when installing 3rd party libronix books. Plus, it doesn't take much space on your HD and you can have the best of both worlds.
