DashDoc can not work after installing both zeal and velocity and uninstall zeal

[jdhao]

I first installed velocity and DashDoc for sublime text. The doc search works well and use velocity. I then installed zeal. The doc search works well and use zeal. I then decided to uninstall zeal. After that, DasDoc does not work any more.

When I invoke the doc search function using my custom shortcut key, DashDoc complains that it can not find the application.
