Older Versions

Note that .NET Framework 4.5.2 uses the same CLR (Common Language Runtime) as .NET Framework 4.0, so if you are using .NET Framework 4.0, you should have no problem upgrading to .NET Framework 4.5.2.

If you cannot use .NET Framework 4.5.2 but can use .NET Framework 4.5, consider downloading QuickOPC 5.35 instead. Also consider one of the past versions if you need to run on an older operating system. Note that support for older versions is limited.
