Firefox cannot find VC Runtime140_1.dll

Firefox install fails because it cannot find VC Runtime140_1.dll I downloaded the dll but Firefox can't find it. Where should I put this .dll? The bulk of the program installs but it can't search on line.

This is a new Win 10 machine. I've updated and ran DISM.exe /Online /Cleanup-image /Restorehealth then uninstalled Firefox, put the VCRuntime file in the Win Sys 32 drivers folder, restarted and reloaded Firefox. Still no love.

I'm at the end of the road...what next?
