I have tried the Installer fix error that people were getting installer errors
I should have asked earlier, but since you started a new thread, I don't know what you did to perform this installer issue.
If you could describe that further, i could possibly help more.
In IE, save the file directly to the desktop.
Let me know what happens
Since all Windows updates create a restore point, see if you can go back to an earlier date, then install each update separately.
Try going to C:\users\yourname\AppData\Roaming and delete all references to Firefox. Firefox only, don't delete any other files in that directory.
Then go to C:\Users\yourname\AppData\Local\Temp and delete all files and folders.
Also go to C:\windows\temp and delete everything in that folder.
When uninstalling programs I suggest you use a freeware utility that cleans out more junk than the typical uninstall program does. it's called RevoUninstyaller and you can download it here:
Revo Uninstaller Freeware - Uninstall Software, Remove Programs, Solve uninstall problems
Then try re-installing Firefox.
Excellent,
I was going to mention the registry, but I didn't know if you were an experienced user and new the registry structure.
Even after doing an uninstall using Revo, I use another program to make sure it's completely gone.
It's called RegSeeker and can be downloaded here:
|MG| RegSeeker 1.55
Make sure to look over the entries very carefully, before removing items. Regseeker does keep a backup in .reg format if you need to undo the changes.
