I am running TI Home version 9, Build 2337. In general, it is working for me. Should I update to Build 3854? Does it provide anything in terms of reliability or features I don't have now? Or should I go right to to version 10? If I do update/upgrade, can I do it in-place, or should I remove the current Build first? If I should uninstall first, can I do it in Control Panel Add/Remove or do I need to run a manual uninstall utility or make registry edits? Sorry for all the questions. Appreciate the feedback.
