How to update C++ compiler used by visual studio 2017?

Sebastian 1 Reputation point

I am using Visual Studio 2017 to develop C++. I found there is a bug in the compiler, so I need to update it to a newer version. How can I do this? Do I have to install a newer version of Visual Studio to get it, or is it possible to get the newer compiler from within my current version of Visual Studio?

According to cl, my compiler version is: 19.16.27048.

Using godbolt to compile online, I find that my code compiles for 19.16 and later. (Probably the 19.16 godbolt is using is a later version than mine). So I need to update to a later version of 19.16, or something like 19.20 or later.

I'd prefer to update the compiler without having to install an entirely new version of visual studio if possible.

    Hi @Sebastian ,

    Welcome to Microsoft Q&A forum.

    I’m afraid, the Microsoft C++ (MSVC) compiler toolset used by VS, cannot be updated separately. You may need to update VS to update the compiler toolset.

    Best Regards,
