Hello, I'm one of the Developers on Ashes: Escalation, I'm sorry to hear you are having problems.
If you still have any of these three files in your Ashes install directory, please delete them and try again.
msvcp140.dll
vccorlib140.dll
vcruntime140.dll
We mistakenly distributed them with an earlier version of the game, but they are not required, and they can cause problems on Windows 7.
Let me know if that works.
