Please re-install this application.
Most likely this problem is due to a failed installation of the Visual Studio 2015 C++ redistributables on your computer. Probably because it was interrupted at some point (the installer might need 10 minutes or more to complete on some systems) or other processes are blocking its execution. Please take a look at this Microsoft site, were several methods are described to overcome this problem:
Try method 1 in the following way:
1) Download the files
- vc_redist.x64.exe
- vc_redist.x86.exe
from:

2) Start your computer as described with a clean boot:

3) Install the redist files. If they happen to be already installed, they will offer an uninstall option. If this is present, first uninstall both of them, restart (clean boot) your computer and then install them again.
4) Don’t forget to reset your computer to start as normal and restart it. EEP Train Simulator Mission should run now.
