There is an update to RW to 6.3.7 or the new beta 6.3.8 that fixes a lot of these issues (perhaps)
Also, for the update/duplicate message, here is my reply in a previous thread…
Lastly, are you using some sort of “disk cleaning utility” to help remove unwanted files/duplicates or language files? If you are then these cause app problems, stop using it and remove from HDD. Simply restarting OSX fixes A LOT of issues.
Food for thought…
