I HAVE JUST GOTTEN A COPY A SIBELIUS 5 AND WANT TO MAKE SURE ITS' SETUP CORRECTLY. I ALREADY HAVE VDL WORKING WITH FINALE 2007C. IS THERE ANYTHING I NEED TO REINSTALL, REMOVE, COPY, ETC. I DON'T WANT TO MESS ANYTHING UP WITH EITHER PROGRAMS.
So you have Finale 2007 already, now you're adding Sibelius 5? This shouldn't affect anything in your pre-existing setup. The one thing you might need to do is *copy* the KontaktPlayer2.dll file into the Sibelius>VST Plugins folder. This will ensure that Sibelius actually recognizes Kontakt Player 2 as a plugin which you can use within the program.
