What version of .net framework work on windows 7 pro build 7600 ? And must be offline installer.
As I understand it, Windows 7 Build 7600 comes with framework 3.5 but you can download and install Framework 4 from https://www.microsoft.com/download/details.aspx?id=17718
The next version up Framework 4.5 requires Windows 7 SP1.
Build 7600 means that it's the final version of Windows 7, thus it should be compatible with anything supporting Windows 7 SP1.
The "Professional" edition aspect of your OS won't affect compatibility as it just refers to extra software that was bundled with that release; so again, for compatibility purposes this is just Windows 7 SP1.
Microsoft .NET Framework 4.6.2 supports Windows 7 SP1 and has an offline installer.
The Microsoft .NET Framework 4.6.2 is a highly compatible, in-place update to the Microsoft .NET Framework 4/4.5/4.5.1/4.5.2/4.6/4.6.1. The offline package can be used in situations where the web installer cannot be used due to lack of internet connectivity.
You can download the offline installer and review the installation instructions here:
