I have formate my computer. And of course everything is gone. Now Í want to reinstall F-secure safe. This seems impossible. I don´t know what to do.
It would help if you explained more on what the issue is in general with your install, (IE) F Secure login, downloading issue, some source of disconnection or the software refusing to install.
Their could be any number of fixes if we knew what we were looking for, hopefully i can help more indepth once you provide some information.
You can reinstall F-Secure from the SAFE Portal. It doesn't matter if it is still listed in your portal, as when you reinstall, it will give you the option to reuse an existing license, so your new installation license will continue from when it was last active.
