Update
Okay I deleted the C:\Users\****\AppData\Local\Autodesk\3dsMax\2016 - 64bit for the second time and its up and running !!!
Thanks Maru,
I can't even get a minidump from 3dsmax, the "crash" window doens't come up.
I double click 3dsmax 2016 icon, 3dsmax splash screen comes up and just sits there, I can leave it and nothing happens.
