Summary, if you install the 'Cakewalk Content' somewhere other than C:, beware!
I installed Rapture Pro on my laptop which has only a C: drive and uses all the default installations.
However, on my workstation DAW, I have 14 drive volumes in use and I have various parts of installations on various volumes.
After installing, the laptop shows a log file in
C:\Cakewalk Content\Logs\rap2-log-apr28.txt
It has 4373 entries and lots of errors like this:
18:55:01 [ C:\Cakewalk Content\Rapture Pro\Programs\Rapture (legacy)\Galbanum Piscis\2 - Multiwave Pads\Bradypodion Pad.prog ] Loading Program

But on my workstation, the Cakewalk Content path is at
K:\Cakewalk Content\
and there is not a single 'Logs' folder anywhere on the K: volume.
