This error could be caused by installation of new software, and has been reported after installing recent Windows Updates.  The most likely cause is due to missing or corrupt Runtime components for the Visual C++ libraries. To resolve the error you should download and install the 32-bit Microsoft Visual C++ Redistributable Package (x86) from the Microsoft download page or directly using the following link: [https://aka.ms/vs/17/release/vc\_redist.x86.exe](https://aka.ms/vs/16/release/vc_redist.x86.exe) You may be required to uninstall the existing Microsoft Visual C++ 2015 Redistributable Package before installing the latest Microsoft Visual C++ Redistributable Package. -
