Latest RC8 hanging on startup on AWS EC2

heya devvvvs

just tried running latest beta39 preview (RC8) on a virtual amazon machine with the following specs:
OS: Windows Server 2016
CPU: E5-2686 v4 @2.3GHz
Nvidia Tesla M60

Throws an exception when launching vvvv.exe (see startuplog below) and then hangs on the splash image. 50beta38.1 runs fine on the same machine. Any idea?

dump of startup log:

this should be part of the .NET standard stuff, does that machine have .NET 4.7 installed?

Yep, installing .NET 4.72 solved the problem. Thanks MicroD!!

@hengge did you download the .zip or did you use the installer? the installer should check for net 4.7 and install it… that can take quite a while. did you see this happening? or maybe cancelled the setup process?
