I am currently using 2014 on a Windows 7 machine and I'm thinking about upgrading to 2016. I have no intention of or desire to upgrade my OS at this time, so I need to be sure 2016 will work with Windows 7 before I buy.
I just tried the upgrade from MEP 2015 to 2016 today and it keeps locking up on my W7 system when doing simple editing and trying to output anything in regular file formats. At least the 2015 version would go several days before having a lock up that required a Task Manager termination just to get my files back. I don't know if this is going to be bearable even. I also hope I will be able to go back to using the 2015 version if I do manage to get this off the system without too many ghost effects.
Just a point of information.... I took the plunge to upgrade MEP 2015 Plus to the 2016 version and was surprised (and so it seems were Magix!) that it refuses to load bog-standard AVCHD files from my Panny HC-x920 with which the 2015 version works perfectly. It would seem, hopefully, to be a relatively minor bug that somehow crept through their quality control.
So until the good Ralf and his colleagues can sort it out, I've gone back to "another" editor.
From my experience MEP 2016 doesn't seem to be compatable with anything. Everyhing I try to do with this software turns out to be a waist of time. I have repaired and reinstalled multiple times and still can't get it to burn a DVD (encoder error) or stop locking up in the middle of....well... pretty much eveything I do. If Magix does not have a patch or upgrade to fix these problems I will be forced to dump Magix after 8 years of use.
