Cannot update to ESET NOD 32 Antivirus 8


Go to solution Solved by janneke.cj,

Recommended Posts

Hi, I can't manage to update version 5 to NOD32 Antivirus 8. I get a message that the installation package is unfindable. See attachment (I'll translate the Dutch message):

 

Cannot find the path C:\ProgramData\ESET\ESET NOD32 Antivirus\Installer\ei_4DE2.msi. Check if you have access to this location and try again, or search the installation package ei_4DE2.msi in a folder from which you can install the product ESET NOD32 Antivirus.

 

When trying to deinstall, I get a comparable message: the network course is not available.

 

How can I solve this?

 

Many thanks in advance!

With best regards,

 

Janneke

It seems that the original installation file C:\ProgramData\ESET\ESET NOD32 Antivirus\Installer\ei_4DE2.msi needed for uninstallation was removed from the system. Run the ESET Uninstall tool in safe mode instead.

 

Hi Marcos.  I have the exact same issue.  Are saying ESET expects us to go through all this just to do an update???  I respectfully submit that this is utterly ridiculous!  ESET needs to get this figured out and re-release a working update - and pronto.  Appreciate the assistance and willingness to help, but this is something I'd expect to have to do for a start-up software firm, not ESET.  I mean serious, all this.....  THIS IS FREAKING NUTS!

Back up network adapter settings

After using the ESET Uninstaller Tool, you may be required to reinstall your network adapter drivers. Follow the steps below to back up your network adapter settings and restore them after uninstallation is finished:

  1. Before running the Uninstaller Tool: Open an administrative command prompt (Right-click the Start icon, select Command Prompt (Admin) from the context menu and click Yes at the prompt) and enter the following command to back up your network adapter settings:
    • netsh -c interface dump > c:\NetworkSettings.txt

       

  2. After uninstallation is complete: Reinstall your network adapter drivers if necessary and then open an administrative command prompt and enter the following command to restore your network adapter settings:
    • netsh -f C:\NetworkSettings.txt
  1. Download the ESET Uninstaller (650 KB) and save it to your Desktop.

     

  2. Uninstall the Epfw NDIS LightWeight Filter:
    1. Press the Windows key windows_key_icon.jpg + r to open a Run dialog, type ncpa.cpl into the blank field and then click OK.

       

    2. Right-click your network adapter (select Wireless network connection) and select Properties from the drop-down menu.

       

    3. Select Epfw NDIS LightWeight Filter and click Uninstall. Click Yes at the prompt, uninstallation may take several minutes.

  1. In the command prompt window type cd Desktop and press Enter.
    • In some cases, the ESET Uninstaller utility will need to be launched by typing ESETUninstaller.exe /reinst into the command line and pressing Enter. The ESET Uninstaller utility will prompt you if the above switch is necessary.
    • If you are prompted to use the ESETUninstaller.exe /reinst command, your Network Interface Card settings will be reset. We recommend that you record your network settings somewhere so that you can easily reconfigure them after running the uninstaller tool.

       

Advanced user commands
: To view a full list of available commands for the ESET Uninstaller, type ESETUninstaller.exe /help.

  • If you are removing ESET products from bootable media you will be asked whether you want to remove ESET files from each available partition separately.
  • The /mode=offline parameter specifies the uninstallation mode for CD and USB drives.
  • The /mode=online parameter specifies hard disks. Very rarely, you may need to
    use the /mode=online
    parameter to force the ESET product file deletions if the ESET Uninstaller does not detect your bootable media automatically.
  • To remove all present antivirus installations without being prompted, run the uninstaller with the /force parameter.
  • If the ESET Uninstaller cannot be
    used
    successfully in Safe Mode,
    disable self-defense in your ESET product and restart your computer.
    Run the ESET Uninstaller again using the /nosafemode parameter
    .

  1. Once the ESET Uninstaller tool is finished running, press any key to exit and then restart your computer in normal mode.
    • The uninstaller writes a log of all its processes to the ~ESETUninstaller.log file (located in the same folder as the ESETUnistaller.exe file) for future reference.

  1. Click the link below that corresponds to your ESET product for help with reinstallation. If you continue to experience issues with reinstallation, delete the ehdrv driver using device manager and then repeat the steps above to run the ESET Uninstaller application again. Because ESET is designed as a security application, in some instances multiple attempts are required to uninstall the product completely.

Definitely not. ESET products uninstall normally like any other software and the Uninstall tool should only be used if the standard uninstallation fails. In your case it's failing because the original installation file C:\ProgramData\ESET\ESET NOD32 Antivirus\Installer\ei_4DE2.msi was removed (maybe by a disk cleaner or you removed it in order to save some space). Alternatively you could fix this by restoring that msi file, either by getting the original installer and placing it in the above mentioned folder with the said name or copying it from the c:\winsows\installer folder (it may be difficult to find it among all the installers but if you focus on those that are about 70-80 MB in size, you should be able to find it reasonably quickly).

Marcos -  I know you're not implying I'm a newb, but only a newb would accidentally delete an MSI.  Because ESET is functioning fine, I attribute this to the install package of the latest release.  Every update I've ever done (going back YEARS) has been 100% painless and thought free.  Now that I've upgraded to W10, that trend seems to have taken a sharp 180.  I will wait for the next release or whatever.  Not impressed right now, so feel free to relay that up the flag pole.  Thank you for your time.
