Bought a new computer that was supposed to come with Windows 11, but came with Windows 10 and right to upgrade. Set up computer, downloaded Firefox, and it ran fine. after a couple of hours, ran the upgrade to Windows 11. Firefox stopped opening. uninstalled then reinstalled Firefox several times, but each time during installation get the following message (image below):

"C:\WINDOWS\SYSTEM32\MSVCP140.DLL is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f."

Have tried installing with and without defaults, and refreshing instead of reinstalling.

I will be moving all of my data to a new laptop and want to know if I need to have both my personal Firefox profile and the "default-release" profile backed up. The "default" one is over 3GB and has over 20k files in it, and my personal one is only 113 MB with 1300 files — and my thumb drive needs all the extra space it can get. (Why would the "default-release" profile be so much larger than my personal one?)

The old laptop runs on Windows and the new one will have the Linux OS. Will that make a difference in using a backed up Firefox profile? I mean, will the data still work in the new OS?

My e-mail address changed, but the old one keeps popping up. I need to ELIMINATE the old one and use ONLY the new one. I've told various organizations, businesses, etc., to make the change. I want Mozilla Firefox to ELIMINATE the old one and use ONLY the new one. Help!
