Maybe something here?

How to fix the Update Failed error message when updating Firefox

do have a solution?

Did you try any of the solutions in the article I linked?

I even tried to deleat the entire firefox program and reinstal but it will not allow me to do that. it just keeps asking me to reboot.

The first suggestion is to manually install Firefox over your current version. (Download the new Firefox version from http://getfirefox.com and then run the installer - see How to install Firefox on Windows for details.)

There are other solutions after that you can try .... the last one is to Run as Administrator.

thank you

I will try what you suggested
