I currently have Portable Firefox 11.0 on my machine. I downloaded version 12.0 last night but when I tried to install it just as I did since version 3.6, it gave me the error that the path is not valid. This is the same directory that I have been using since version 3.6 (c:\program files\applications\internet applications\portable mozilla firefox). I tried to copy the file into the directory and tried to install it from there, but I still got the same error. Does anyone have the same error or know how I can fix this problem? I don't want to install fresh and lose all of my setting. Thank you!
