Error message every time Firefox starts up
I receive the following error message when starting FireFox.
Title: IAM.exe - Entry Point Not Found. Error: The procedure entry point ucrtbase.terminate could not be located in the dynamic link library api-ms-win-crt-runtime-l1-1-0.dll
Clicking OK on error causes the dialog box to pop up again immediately. I have tried uninstalling and reinstalling Fiirefox, but it doesn't solve the problem. A screenshot of the error is attached. Please note that while the error box is showing, I can still use the browser. But, I'm unable to dismiss the error message altogether and the dialog box is always visible on the page.
The dialog box only disappears once Firefox is shut down.

In general, this looks like you either need some Visual Studio runtime update (Visual C++ Redistributable for Visual Studio 2015), or some other updates for Windows if you don’t have it installed. Is your Windows up-to-date?
