Just downloaded latest 4.10 and getting api-ms-win-crt-runtime-l1-1-0.dll missing from computer. Try reinstalling, which I did and also tried installing api-ms-win-crt-runtime-l1-1-0.dll from dll fixer (Thought was worth a try). Anyone can help? It is driving me insane XD.
Using windows 8.1 pro, and Visual C++ Redistributable Packages for Visual Studio 2013)
Not sure about it but 4.10 is using 2015 runtime, so update it
