cannot install internet explorer 11 in Windows 7 Pro

Go to Programs and Features, Windows Features and uncheck IE.  Restart (you must). Go back and enable IE. Restart again (you must).

What version of IE do you now have?  
If need be can you now reinstall IE?

If no to all the above:

1. Open cmd.exe with Run as Administrator. Run SFC /SCANNOW and allow to complete. Restart and check IE.
2. If still no, run a Windows 7 Repair Install from the Windows 7 DVD or the on-board recovery partition.

uninstall antivirus software, restart computer and do a windows update and restart computer and try to install IE11 again.

I have Internet Explorer 8 and have no problem reinstalling it if I only knew how.  I followed your instructions and was not successful.  It is a Dell OptiPlex 790 and I do not have a Windows 7 Pro x64 install DVD.

Have you tried my approach?

I uninstalled the Anti-virus and rebooted the PC --- still no success.
I am also unable to install 43 Windows updates -- get error code 8000FFFF.

Unable to get updates is your issue . Run a Windows 7 Repair Install as your machine has more issues than just IE 11

Method 1: Run the
Windows Update troubleshooter and check if you’re able to install the updates.

‘Open the Windows Update troubleshooter’

http://windows.microsoft.com/en-US/windows7/Open-the-Windows-Update-troubleshooter

Method 2: Start the
computer in clean boot and then follow the steps provided in the following article and check if that helps. To configure your computer to clean boot refer the following link.

Note: After you have
finished troubleshooting, follow step 7 in the article to boot to normal startup.

‘Unable to install updates in Windows Vista, Windows 7, Windows Server 2008 and Windows Server 2008 R2;

http://support.microsoft.com/kb/2509997

Method 3: For issues
with the computer running slow, run the fixit provided in the following link and check if the issue persists.

It is not an easy task. You need a friend who has Dell Win 7 Setup DVD to help you to do a clean install if the above methods do not work.

If you can launch Repair Install it is about the easiest method but takes a while once it starts.

Fresh install would be my last resort but it is pretty much guaranteed to work

OR
Contact Dell to buy recovery DVD for your model (you can also check in your list of installed programs to see whether there is a Dell recovery software to do a factory reset. - Just search for Dell and you will find out.)

I will have to find a Dell Windows 7 DVD.  
There is nothing else I can do to repair this?
Also, if I run this repair DVD, I need to be sure I do not wipe out any programs I installed.

The Windows Repair will Keep Everything. It does for me but no guarantee if the machine is in really bad shape

It will be very difficult for you to find one Dell Win 7 Setup DVD.

If you use any Win 7 Setup DVD (other than the Dell one), the licence of your OS will be deactivated and will not be automatically activated via the Internet and phone activation will fail too unless you try extremely hard to convince Microsoft that you are legally allowed to use the licence from the other win 7 Setup DVD. Of course, if your Win 7 Setup DVD is a retailed version which has been activated for once, it will be fine as you can just tell Microsoft that your old computer had died and you use the setup DVD to setup the OS in another computer.

The way for normal users is to order a recovery DVD from Dell.

The above is my experience only. I ordered recovery win 7 recovery DVD for the computers in my workplace although I have Lenovo Win 7 Setup DVD personally.

The professional approach is to do a factory restore as it will be the safest and legal path.

Besides, all licenced applications which are not published by Microsoft will need to be reinstalled.

I am working on the Windows update Troubleshooter....

The Windows Update Repair Tool found & fixed and repaired the following:
"Service registration is missing or corrupt"
"Problems installing recent updates"

I changed update settings (as per instructions) to "Never check for updates...."
Rebooted PC.

Ran the Troubleshooter again.
Was not able to fix Windows Update Error: 0x80070005.
Followed instructions on this site:  https://neosmart.net/wiki/0x80070005/#Fix_1_Allow_user_full_control.
Rebooted.
Trying updates now........

If you are trying to fix updates, another very good tool is Windows Offline Updater

http://download.wsusoffline.net/    <--- WSUS Offline does work well

When you install Internet Explorer 11 for Windows 7, the installer program tries to automatically install some prerequisite components. If this part of the installation fails, Internet Explorer stops the installation process.

Windows Update Error: 0x80070005,  it Sounds like a connection issue. Check your network settings and antivirus / Windows firewall settings or just simply try later.

Download the System Update Readiness tool for your Windows 7 and run It to check if it can fix some corruptions.
https://support.microsoft.com/en-us/help/947821/fix-windows-update-errors-by-using-the-dism-or-system-update-readiness


Did you install service pack 1 for Windows 7 and also all IE 11 perquisites updates ?
https://support.microsoft.com/en-us/help/2847882/prerequisite-updates-for-internet-explorer-11

WSUS offline will do all this

You can create an O.S. recovery USB using the Dell tools here...

It is likely the issue is going to IE 11 from 8, try installing 10 before attempting to go to 11.
https://www.microsoft.com/en-us/download/details.aspx?id=39233 To get IE 10 install.

The "Internet Explorer did not finish installing" error message happens when I try to install IE 9 & 10 also.
To: Ramin: I can remote to the PC and go on the internet OK, but network "Troubleshoot Problems" does not work.
The System Update Readiness tool first addressed in the link by Jackie Man will not install on my PC.
I'm going to get a Dell Windows 7 Pro install DVD try to repair it this Monday.

If all above suggestion didn't help to resolve the problem then a Repair install for Windows 7 will not probably fix this .
Backup your data and be repair for a fresh install.

check if your system has windows SP1 installed - it is needed for installing IE11

It already has SP1.  

It appears to me that the message indicates that the install process started, but did not complete.  My experience with installing anything has always been that if the process does not complete, I need to check install logs to see where it stops and correct it.  Wouldn't something be seen in the CBS log or the event viewer?

Also, Windows updates are so important with the security of any Windows PC.  Since Windows 7 is still supported by Microsoft, wouldn't it make sense that Microsoft should support this issue?  It would not look good for them to be saying that I need to perform a clean install of Windows just to fix an update issue (I didn't count all of them, but it already has close to 200 updates installed).

maybe you need to install more updates first (it may also install IE11 as an update
another thing to try is downloading it again,  - it may have been corrupted somehow - and try again

I think, IE is an optional update.

Most of the Dell systems have "Dell Factory Image Restore" option and for this you won't even need the Windows 7 DVD.

Please follow the instructions in the link below to check if you have that option and how to repair your Windows.
