3ds Max User since 2009 and 2017 is my last upgrade since Autodesk went the subscription route with non-perpetual licenses; just like Adobe with their Creative Cloud. 2017 will not shut down clean without a script to kill process and tends to crash on me at the least opportune times; often when doing some of the simplest things. Like their improvements to UVWunwrap but in general I thought 2016 was more stable, it shut down without needing a get process, kill process script and filling my error log with errors every time I'd close it without that script.
