This morning I went to go into Firefox, a message came up stating it was updating. After the update, Firefox didn't open, so I clicked on the icon and got this message. C:\Program Files (x86) Mozilla Fire\firefox.exe. The application has failed to start because its side-by-side configuration is incorrect. I tried removing & re-installing and I even try the Window's restoration point of a couple days back and I still get the message. Has anyone had or have this problem?

Thank you for replying and please be patient, but I'm not familiar with this forum nor this web site. How do I get there to look up your response.

You can click the link in my above post if you haven't done that yet.

That SxS error seems to be caused by a corrupted Visual C installation that requires some DLL files to be reinstalled.
