For a start, I have Windows 7 Ultimate, with this operating system I have previously worked the NMM in its old versions, but with the update that applied the NMM requires the .NET Framework 4.6 or higher, (I currently have the .NET Framework 4.5.2) this has complicated me a lot, since the NMM program requires me to install the latest version of the .NET Framework for its operation, but ... when I try to download it or update it on the official windows page it says no Is compatible with my current operating system, which I need to have Windows 7 SP1, this is quite annoying since I do not want to make any changes that may affect my computer, then I would give developers or users help me with this problem, either That make the earlier versions of the NMM downloadable, or that the NMM is compatible with most versions of the .NET Framework. I would appreciate a prompt solution.
