Avid Support: Avid Sibelius 7 ReWire Uninstall and Reinstall for Windows
Instructional video showing how to completely remove Rewire from your Windows machine, so it can be reinstalled cleanly. This can help when Sibelius 7 is not starting in Rewire mode properly, or it is not showing up as a Rewire slave option in your Digital Audio Workstation host software like Pro-Tools.
You can also follow this procedure if you want to remove the Rewire capacity of Sibelius from your machine altogether as you don’t intend to use it (just ignore the steps in the associated article regarding uninstalling/reinstalling Sibelius 7 afterward if this applies to you – only do steps 1-3).
For additional instructions follow the guidelines in this Avid Knowledge Base article.
