fads
Now I see they have sold out to Bandland.
I can't sleep. Someone is 'wrong' on the internet.
Gibson shut down Cakewalk, Inc in November 2017. That ceased any development of SONAR and ceased lifetime updates as well.
In March of this year BandLab bought the Cakewalk assts.
The was no "selling out". More like BandLab resurrected the product and is now calling it Cakewalk by BandLab.
CbB (as it is lovingly referred to) is now in early release stages while they transition the customer base to BandLab's ecosphere. Which means you need to create a BandLab account using the same email address that you used in your Cakewalk store account. Why? Because one day CCC will be shut down in lieu of you receiving any transferred over products and assets from Cakewalk, Inc to BandLab.
You must install the BandLab Assistant in order to install CbB (and other assets now and later). You must have online ability for the computers(s) you plan to install on. There is no offline (yet) installation capability. And finally there is no 32bit version of CbB, it's only 64bit and it seems likely it will never be 32bit (but I've been proven wrong before).
Now the good news is anything "Cakewalk, Inc." you have installed from CCC or earlier will continue to work in CbB. So it is wise, for now, to NOT uninstall SONAR Platinum.
