Hi,

Since I updated to the most recent version, Firefox hasn't worked.

When clicked, Firefox doesn't launch, no error message shows, and no processes appear in task manager.

I have uninstalled and reinstalled, deleted the folders and reinstalled, run as administrator with no change. If there is anything else I can try, please let me know.

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.
