Net Framework 4.5 Download Windows 7 64 Bit Fix Now

If no legacy software explicitly demands 4.5 (by checking manifest or error message), install .NET Framework 4.8 instead. It is backward compatible and more secure. Final Verdict Yes, you can download and install .NET Framework 4.5 on Windows 7 64-bit using Microsoft’s official 4.5.2 offline installer. However, for long-term stability and security on an already outdated OS, migrate to .NET Framework 4.8 whenever possible.
