Problem: The Melodyne Essential 18.104.22.168 that came bundled with Pro Tools 8 LE keeps failing its install. It gives the following error excuse: Install Failed. The Installer cound not install some files in “/”. Contact the software manufacture for assistance.
Solution: The installer is having writing over the existing Propellerheads ReWire plugin. I used the Terminal App to first delete the folder and its contents, then create a new empty folder of the same name. This will probably come back to bite me later (but I’ll deal with it then).
