I just went to re establish the use of my SX 15 it has a Parallel interface & Dr Stika won't work with Win10 - I purchased a USB to // interface from a local e'nics store & approached the Local Roland Distributer they sent me a dropbox link to CutStudio (normally not downloadable) & links to the Japanese/English Drivers site I ended up installing the version 1.3 Win 10 drivers for the SV15 ( I needed to disable driver signing) & I got the Illustrator CC plugin from Adobe & the Parrallel SX15 now works on a upto date Win10 system - it took a little bit of a fiddle in that I installed it as a parallel printer 1st then changed its printer port in properties to the USB port occupied by the adaptor.
I have assumed that Roland don't want to globally make CutStudio available but they freely responded with the Dropbox link when I asked for help via the web help page on the local Roland Distro site - I'm in Australia for reference
I hope that helps
Regards
Stephen
