Hi with the latest windows 10 update for flash KB3133431 on 6 Jan 2016 and with the Poser 9 Service release 3.2 (WIN Version*: 9.0.3. 26132, Released 11/25/2013) from Smith Micro - http://my.smithmicro.com/poser-9-updates.html

I was able to install Poser 9 and it now seems to be running OK on Windows 10, it doesn't crash on start up and the library is working
