Has anyone had this?

"firefox.exe is not a valid Win32 application"

This warning comes up when Dreamweaver needs to open Firefox.

On my system, it's located in Program Files (x86) > Mozilla Firefox > Firefox.exe.

I already had added Firefox to my list.

However, what has fixed it, was removing and reinstalling Firefox.
