# vcruntime140.dll vs vcruntime140d.dll

What are the difference between these two dlls vcruntime140.dll and vcruntime140d.dll? Why do we need them? Are they both part of the Microsoft Visual C++ 2015 Redistributable?

Have googled for quite some time, but couldn't find anything that I can understand.

Some background: I have a C# program that works on a Windows 10 machine but doesn't work on Windows Vista, and looks like it is because there is no vcruntime140d.dll on my Windows Vista machine.

• a release version which does NOT end with a d - for example: vcruntime140.dll
• a debug version which ends with a d - for example: vcruntime140d.dll
