1480837 2021-09-24 09:02:00 Can't run Firefox. Reinstalled the latest version, same error:

"
firefox.exe - System Error

The code execution cannot proceed because VCRUNTIME140_1 was not found. Reinstalling the program may fix this problem"


Have been using FF for many, many years, never had this before.


How to fix it?

OS: Win10 Pro with latest updates

1480838 2021-09-24 10:23:00 When you uninstall Firefox the profile is still left on the computer, you should probably delete it but before you do first try a Portable version to see if that works. It can be installed to a folder anywhere and tried out without interfering with your existing Firefox profile, the desktop is a good place to install it.

Get it from here:

softwarekeep.com

Go to this part of the page:

How to Fix VCRUNTIME140.dll is Missing Error on Windows 10?

Re-register the VCRUNTIME140. DLL file.
Run System File Checker.
Reinstall the latest Visual C++ Redistributable for Visual Studio 2015.
Repair Microsoft Visual C++ 2015 Redistributable.
Run a PC repair tool.
Reinstall the program that cannot be launched.
Install Windows Updates.

Let's discuss these methods in detail and so on,

I'd try Run System File Checker first.
