Setup with green progress bar ran pretty much to the end (was getting coffee)
and now the Setup - Cakewalk by BandLab window has a red progress bar and under it this dialog:
"Error
C:\Program Files\Cakewalk\Shared Utilities\CW130Auto.dll
Unable to register theDLL/OCX: RegSvr.dll failed with exit code 0x3.
"
Abort, Retry, Ignore (not recommended)
Retry just re-opens the error dialog.
