Just joining the Cakewalk community and initially I was getting the reporting hanging on 0/1.
The answer was to run Bandlab in administrator mode and then be patient - the files are very big ...
Cakewalk_by_BandLab_Setup_27.06.0.058.exe 562 MB
drumReplacer.exe 252 MB
instruments.exe 920 MB
melodyne.exe 65 MB
themeEditor.exe 19 MB
To reassure yourself that something is happening open C:\Users\<user>\AppData\Roaming\bandlab-assistant\Downloads and keep an eye on the file sizes
