I tried to start Visual Studio and it said: "This application has failed to start because ATL100.DLL was not found. Re-installing the application may fix this problem".
I don’t want to reinstall it (time consuming).
I also just uninstalled all the C++ stuff (I don’t do any C++ work, so I got rid of it).
So does anyone know?
If the ATL100.DLL is missing you’re likely just seeing the first missing file of a now corrupted installation. If you don’t want to do a full reinstall you can attempt to repair the installation from your install source but there’s no easy fix for this.
