[Romulator]

Problem A8 of the Troubleshooting Guide suggests installing the following.

8. (Windows only) Install Visual Studio runtime dlls
Try installing these:
https://www.microsoft.com/en-us/download...x?id=15336
https://www.microsoft.com/en-us/download...x?id=21254
https://www.microsoft.com/en-us/download...x?id=14632

These should be installed when you start the game the first time, but in rare cases it might fail.

You might even have to uninstall the runtimes first and then install them again. Before you do this though: Make 100% sure that your OS is 64 bit

You may, if you have a 64-bit system, also require the 64-bit variant of the download specified in the earlier thread.
