Corona, 3ds Max and Microsoft .NET Framework problem

[fadlabi]

Hi, all
Yesterday i tried to experiment to render with Corona, and every thing is go ok. After i saved the file and coming this day to open there's an error message from Microsoft .NET Framework:

I have uninstall .net framework 4.5.1 then install again but the problem still exist, when i open any other 3ds max files without any corona rendering setting there no problem.

Windows 7 64bit
3ds Max 2015
Corona V7
