How to update
Got a very simple question. Maybe to simple cause I can't find an answer, but I don't want to risk screwing anything up. I run calibre on my pc os windows 7. To update to newest version of calibre do i have to uninstall first? Or just dl new version then run loader/instaler without uninstalling current version? Does it matter if i already have calbre open/running with some books open when run install on new version?
