Cannot load Firefox. Message=VC Runtime 140_1.dll missing.

I have been using Firefox for many years. So, I am using Microsoft Bing. It is the only way I can have access to the internet. I have downloaded many times only to be rejected because I am being informed that a DLL file is missing. Again, VC Runtime 140_1.dll is missing
