I installed TE2013 1.0b and bought a key a few months ago and I've been playing it offline. Absolutely love they game. But I now want to upgrade to the latest version and try some of the mods that I hear so much about. How do you recommend I update to the newest version (1.0c)? Do I use the latest demo installer, install to a new folder, then put the Key.txt in that folder? I'm wondering what the safest way to upgrade. Is it okay if I have two or more versions of TE installed at the same time? I was thinking of maybe even have 3 different versions installed at the same time, in 3 different folders: 1.0b, the latest version in case I wanted to play online, and a 3rd install to try some of the offline mods.
Is there any harm in keeping the old versions installed in case they are a little different gameplay-wise than the latest versions?
