"cannot open source file" error

Vladimir Kolmogorov 0 Reputation points

I just installed Visual Studio 2022. I created a new empty project, added file "test.cpp" and tried to compile. It says "Cannot open source file ...\TEST.CPP". (Screenshots are here: test.pdf ). Following suggestions on internet, I installed "Windows SDK 10" and retargeted project. I have Windows 10 Pro (on a virtual machine). What am I doing wrong?

    Hello @Vladimir Kolmogorov ,

    Welcome to Microsoft Q&A forum.

    If you try to change to create a new project and save it in another directory, maybe in other drive, and then add a .cpp file, will the same error appear?

    If the same error still appears, please try to close VS > open VS Installer > More > click Repair to repair VS. Also try to run devenv /ResetSettings in VS Developer Command Prompt to reset VS settings.

    If the same error doesn’t appear, please check if there’s any limitation or special configuration on that drive/directory.

    Besides, please try to run VS as administrator.

    Best Regards,
