| Note: |
| Microsoft Visual C++ Redistributable for Visual Studio 2019 16.7 package (with UCRT version 14.27.29114.0) is really the latest UCRT compatible package for Windows XP SP2/SP3 and Windows XP x64 SP1/SP2 and Windows Server 2003 SP1/SP2 systems. There is available redistributable Visual Studio 2019 16.8 Preview 2 package (with UCRT version 14.28.29213.0) which has higher build number than the 16.7 version, but it is only beta preview version and moreover it was released before the final 16.7 release. So the last released version compatible with those systems is really 16.7 version. |
