Not able to install on Windows 7

I am not able to download manager on Windows 7
It states that it cannot be installed because of .Net framework version lower than 4.5
So kindly guide me how to do it
I have tried it downloading from Internet explorer and google chrome too … But the same issue is arising
Hope to have a good and fast response

Install the update and it should work.

@aymanjou 4.5.2 is an older version. I would install the latest version -
