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

If anyone has problem installing 2015 runtime, you need to have windows update windows update kb2919355 (700 MB) to be installed and for that update prerequisite KB2919442 (10 MB) has to be installed.
