Hello,

Install Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 from here https://support.microsoft.com/en-us/h... and take care about the bitness (32-bit or 64-bit) of your operating system

64-bit: https://aka.ms/vs/16/release/vc_redist.x64.exe
32-bit: https://aka.ms/vs/16/release/vc_redist.x86.exe

Hope that helps.
