The bundled clang-format binary for Windows is built for x64 - should be x86 for compatibility with x86 and ia32 systems.

I try run clang-format.exe
get error
"This version of C:\Users\Marian.vscode\extensions\ms-vscode.cpptools-1.0.1\LLVM\bin\clang-format.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher."

Hi CodeNameHawk . Thanks for reporting this. It looks like clang-format binary bundled with the extension on Windows is built for x64, and should be built for x86 instead.

The manual workaround would be to install https://github.com/llvm/llvm-project/releases/download/llvmorg-10.0.0/LLVM-10.0.0-win32.exe and set the C_Cpp.clang_format_path to "C:\\Program Files\\LLVM\\bin\\clang-format.exe".

Elaheh Rashedi (@elahehrashedi) The x64 clang-format would be useful to keep around in case we ship an x64 vsix in the future.

I changed the pipeline to build the clang-format binary for Win32 target architecture.
Sean McManus (@sean-mcmanus) maybe we should create another pipeline to build for Win64 in the future.

Okay, that's fine.

1. The new Binary needs to be published and the fwlink needs to be updated.
2. The shared folder for offline/insiders builds needs to be updated.
