Windows.NET Framework will not load

I am trying to run SWX Student 2014-2015 on my Intel QuadCore i5-3470 CPU @ 3.20GHz, 16 GB RAM, MS Windows 7 Home Premium v. 6.1 64-bit SP1.

It was assembled by Net Solution Computers of Morley, Western Australia, and has a SAMSUNG U28D590D VDU driven by an NVIDIA QUADRO K620 Video Card and RealTek High Definition Audio on Motherboard MSI B75MA-P45

I have Windows Security Essentials as Anti-virus with IE11 and Skype running in the background.

It won't run because it cannot load Windows.NET Framework.  That is not surprising because I have been unable to load Framework - see files attached.

Would someone please tell me why it did not load, and how to load it.

Thanks
