Aha! That's pretty poor UI. (And so is the bit where it lists Uninstall twice because there are 2 uninstaller.exes there.)
Context menu's seem like a pretty good solution for something that you won't use every time you open the application. If you have some constructive feedback on how we could improve it though we'd love to hear it. Additionally do you see this being an option that you'll use often or would just making a help doc for C3 be enough to point folks in the right direction? (This is still new for us as well - so obviously we haven't refined every use scenario).
You can have two uninstall options for a lot reasons:
a) You installed both the 32 and 64 bit versions of SONAR
b) You have multiple uninstallers on disk in different locations - this is a byproduct of switching formats. Something that we'll be addressing in a future update
