Answer 1

I faced the same problem on a Windows Server 2012 R2. I tried to reinstall Microsoft Visual C++ 2015 Redistributable, but the error was still there. What fix the problem for me :

1. Uninstall Runtime & Hosting Bundle and Microsoft Visual C++ 2015 Redistributable

2. Run the following command to check and repair file system :

   sfc /scannow

3. Run the following command to check the Windows image for any corruption and to perform a repair automatically :

   dism /online /cleanup-image /restorehealth

4. Run Windows Update and install all updates (this can take a while)

5. Install Runtime & Hosting Bundle from https://dotnet.microsoft.com/download/dotnet-core/2.2

Answer 2

After a lot of digging it turned out that the installer for the hosting bundle failed to download Microsoft Visual C++ 2015 Redistributable. That is why all websites stopped working. I installed it manually and resintalled the hosting bundle and everything worked.

Answer 3

download Microsoft Visual C++ 2015 Redistributable here
