Hi all. I'm trying to install Thunderbird on my mom's desktop. She has been using Outlook Express for years, and I want her to get away from that as well as Windows in general (her computer has a true 1.8 GHZ single-core processor and only 512MB of ram). The first thing I did was install Thunderbird on her XP partition, then I copied the .default file to a flash drive and copied it into the folder where I saw that Thunderbird had another .default folder in (although I never created a user for it). I deleted that folder and replaced it with the .default folder from her XP system. I then went to load Thunderbird, and it gave me the error message that is in the title. I restarted Ubuntu, and it still gave me the same error message. I then deleted Thunderbird from the Synaptic, Software Center, and Terminal. Every time I went to re-install it I got the same message when I tried to open the program. I did find a couple of threads here that had problems with the same error, but it was after they upgraded the software. I found a lot of threads on Google on how to convert from Outlook to Thunderbird, but most of them were 2-3 years old, and the instructions were useless.
If you could help me out I'd appreciate it. I've been trying to configure her email now for about two hours, and I have had no success.
