I know more thait is possible to install on win 11. just open inf file and copy the string under [roland.ntamd64.6.2]
%RDID0027DeviceDesc%=RDID0027Install, USB\VID_0582&PID_0033 ; PCR <--- this one
just below the next one [ roland.NTamd64.7 ].
u should have now something like this
[Roland.NTamd64.6.2]
;; Windows8
%RDID0027DeviceDesc%=RDID0027Install, USB\VID_0582&PID_0033 ; PCR
[Roland.NTamd64.7]
;; Windows11
%RDID0027DeviceDesc%=RDID0027Install, USB\VID_0582&PID_0033 ; PCR
I replaced the not supported words with windows 11. then install after disabling driver signature and it's done, ez pz.
