I had Firefox installed as my default browser. Then it crashed and I couldn't 'repair' it. So I uninstalled then tried to re-install but each time that fails because I get a message that VCRUNTIME140_1.dll is not present

Did you recently uninstall an application that was using Visual C+ runtime components?

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017, 2019, and 2022":

You may also have to install the Visual Studio 2013 Redistributable Package. You need to reboot the computer.
