I installed JABB, then installed the KP2 update. All is well, as far as that goes, but there is still the folder c:\Program Files\Jarritan Jazz Big Band, which contains the old KP1 JABB executable.
Of course that executable no longer works, because when I try to load a patch, it complains that the patch was created in a newer version of Kontakt.
What is a safe way of getting rid of the stuff that is no longer usable? Obviously uninstalling it won't work. I suppose I could remove the shortcut from my Start menu and remove any Garritan_JazzVST.dll plugins, but is there a less klutzy way of doing that?
