Windows 7: Can't install Firefox

Can't install Firefox

I decided to give Firefox another try but can't get it to install. I get a window about Group Policy regarding 7Zip. I've tried a new account also as administrator. I've tried deleting my old Mozilla program file folder and starting from fresh but nothing works. Any ideas ?

Hi:

Are you sure you're not infected?
When you say that you've "tried another account as Administrator", are you referring to a Windows user account?

Also, where are you getting the Fx installer?
The only official source is Mozilla.org >>HERE<< (the list of fully localized installers is >>here<<)

Thanks,

Yep, sure I'm not infected - everything else is fine. By another account, I meant another Windows user account. I also meant I've tried running the installer as admin. Googling 7zip, it seems it is part of the installer. I actually prefer Waterfox but I'm having the same problem with that. Yes, I'm sure they're the official installers
I tried getting into Group Policy but it was a bit over my head.

There is nothing having to do with 7Zip in the Firefox installer.

I suggest deleting whatever setup file you may have and starting again, with a fresh download from the link I provided.

Also: those sorts of "Group Policy Restriction" messages can be indicative of malware. Just saying.

Cheers,

Yes, I'm aware of malware. I've scanned the d/loaded files with Malwarebytes - Super Anti-spyware and Avast - I've also tried earlier versions of FF and Waterfox in case there was anything wrong with the latest versions.

Hmm, well that's sure odd.

I am no Mozilla Script Kiddie, and I am just a longtime home user of Firefox.
But I do lurk a lot at forums.mozillazine.org and I have never heard of the problem you describe, with a 7Zip error and a "Group Policy Error" during installation on an uninfected system.

Normally, running the Firefox installer from HERE under a Windows Admin account is uneventful - the process is quite straightforward, as shown here.

If you are getting the same error messages with other browsers and with other versions of Firefox, then that would suggest that the problem is likely on your system, not with the installer files themselves??

I will defer to other, more expert forum members to further assist you.
Sorry I could not help.

Well, thank you for trying - that's what makes this site so great, people giving their time to help others.
I think you're correct and the fault lies with something on my system - maybe some program I installed has changed some setting that FF needs. I'll keep exploring Thanks again.

Hi:

If it were my system, I'd probably head over to one of the excellent, free, reputable computer disinfection forums for help with a look at the system for malware or damaged settings.
It can't hurt and will only cost you a bit of your time.

Alternatively, you might try posting over at the very active, very expert user community at forums.mozillazine.org
I have lurked there daily for many years and just don't recall seeing the problem you report.
Unless there's something obvious that I missed -- certainly possible -- I suspect they may recommend a check for malware on the system, as well.

Sorry I could not help.

Please do post back and let us know how it works out, so that we can all learn.


Good luck!

I've now solved this problem and have FF and Waterfox back on my laptop. It's just after 2am so I won't go into any detail right now - just wanted to say problem solved Will post details later today.

I promised to come back here and explain how I solved the problem I had at the top of the thread.
So, I googled the message from the attachment and found lots of people had the same problem installing programs etc. There was also a short video explaining how to solve it. I read all the comments under the video and it seems it worked for most so decided to give it a go. I replayed the video and copied down all the steps and then shut down after making a restore point. I restarted in Safe Mode and opened 'regedit'
I then followed all the steps and when done I clicked on the FF exe I'd been trying to open and it installed easily. I then did the same with the Waterfox one and success with that too.

Here's a link to the video: https://www.youtube.com/watch?v=0jhB91LL8hA

If anyone with the same problem comes across this thread - here's the steps to take from the video.
Make a restore point before attempting.

Safe Mode - Regedit - Machine - Software - Policies - Microsoft - Windows - safer - Codeidentifiers - 0 - paths
.......and delete Paths

The first 30 secs of the video shows the problem - the middle bit how to solve it and then shows how the problem has been solved.
