I am having to wipe my laptop clean and install Windows 7 Pro. What do I do with my program and library prior to the reinstall?
Frank, welcome to the forums!
If you've allowed Logos to sync technically all you have to do is install from this link: http://downloads.logos.com/LBS4/Installer/Logos4Setup.exe and sign in with your user name a password and Logos will download the rest.
However, if you want to save some download time and/or indexing you can find time-saving instructions here: http://wiki.logos.com/Quick_Installation_onto_multiple_computers
