Today, I installed FM 2019 Release Version: 184.108.40.2063 32 Bit.
(I was working with FM 11, and after going to Windows 10, I encountered the no-PDF/crash problem, and ended up using the CMYK workaround.)
I saw that the PDF output from my new FM 2019 is CMYK(!), but I want RGB -- and FM crashed after generating the PDF, just like with my FM 11.
I read that the October 2018 FM update enables RGB, so I tried updating (Help > Updates). I got an Update Conflict, but I did not see the processes mentioned. I then got an a Error Code 87, which goes away only after I reboot.
