Are you trying to update Firefox?

If so, try using Help > Check for Updates and see if that works.

Even when I do the update thru the help "check for updates", it downloads and then when I try to install I get the same message.

I have a MAC and Parallels for Windows. That it probably the problem.

I am downloading direct from the mozilla webpage since there haave been a number of update downloads that failed.
