It then goes on to say, check path and try again. I created the file path and soon realized that it changes the name of the path each time. Example path: c:\\Users\Karen\AppData\Local\Temp\7zSCAD.tmp\setup.exe Running windows 7, 64 bit and was trying to download the new Firefox 7. When that didn't work I tried an older version and received the same message. I loved Firefox on my old computer which was running XP. I hope that there is a fix for this. Thanks! Karen
