The Bandlab Assistant (6.5.0) has the check box for Melodyne and the Install button grayed out and green as if its already installed.
Melodyne and Melodyne 4.1 Runtime are not intalled on my PC. Any other way I can get this installed or fixed?
BA uses the registry to keep track of what it has installed.
It stores the data in
HKEY_LOCAL_MACHINE\SOFTWARE\Cakewalk Music Software\Cakewalk\Installers
If it finds a record there, the Add-in is disabled.
Remove the record and the option will be available.
Can't give you the exact record name because I did not install the Melodyne bundled with CbB.
Inspect the data in the records and it should be clear which one is associated with Melodyne.
