This C++ application fixes the common "Discord Installation has failed" issue as well as a grey screen Discord on startup (Discord not working).
Open the *.sln file in Visual Studio 2022 and make sure your compiler supports C++20. Also make sure the cURLpp library is installed e.g. using the package manager vcpkg via vcpkg install cURLpp:x64-windows. For the debug build you need dynamic libraries and for the release build static libraries. For the latter, the vcpkg command would be vcpkg install cURLpp:x64-windows-static. Finally build/run/debug as usual in Visual Studio.
Run the application and follow the instructions on the command line. A compiled version is provided under the GitHub Releases.
