Re: Unable to install/repair/uninstall AT&T Net Client 7.0.2

It seems like it may not be completely uninstalled.

 

Please follow the manual uninstall procedures below:

 

Manual Removal Steps
 
1. Navigate to START-> Control Panel-> Add or Remove Programs, select the AT&T Net Client.  If present, highlight AT&T Global network client and click CHANGE.  Select

REMOVE and select the option to remove all user settings from this computer.
Reboot the workstation.

 

2. Click on Start-> Control Panel-> Network Connections.
In the LAN or High-Speed Internet section find the entry for Local Area Connection.
Right click on the entry and select “properties”.
Scroll down the list of items in the “This connection uses the following items” section.  Look for AGN Filter interface and AT&T Wi-Fi Support Driver
If you see either highlight that entry and select uninstall.
Reboot the workstation if you had to uninstall either or both entries.  Otherwise move on to step 3

 

3. Click on Start-> Control Panel-> System
Select the hardware tab and then device manager.
At the top, click on VIEW and select "show hidden devices". 
Expand or ‘open’ Network Adapters and look for ‘AGN virtual network adapter’ or any AGN component listed. 
If either or both of these entries exist, right click on the entry and select ‘Uninstall’
Reboot the workstation if either or both entries were uninstalled.  Otherwise move on to step  4.

 

4. Download the Windows Installer Clean-Up Utility from http://support.microsoft.com/kb/290301?wa=wsignin1.0
   This URL http://support.microsoft.com/mats/Program_Install_and_Uninstall  takes you directly to the tool which URL should we use?
   NOTE – your PC will reboot after running the below procedure
 
        After downloading the utility run the installation.
 After the installation is complete an option will appear select Detect problems manually.
 A question then appears asking if you are having a problem installing or uninstalling select Uninstall.
 Select any products containing the words “AT&T Global Network Client”
 After selecting these entries click on YES to uninstall and cleanup
 Leave defaults to uninstall and click NEXT
 

5. Right click on START -> EXPLORE
Click  on the “Tools” drop down menu, and select  “Folder Options”.   This will bring up a widow with three (3) tabs. Click on the center tab titled 'View'. On the

Advanced Settings list you will see an option titled 'Hidden Files and Folders' make sure that the 'Show Hidden Files and Folders' radio button is selected. Click on

Apply in the bottom right hand corner and then OK.


Delete the directory C:\Program Files\AT&T Global Network Client

Delete the AGNS folder from C:\Documents and Settings\"logged in user name**"\Local Settings\Application Data\

** Logged in user name generally refers to the user name you log onto the windows desktop with

Please check each username defined under Documents and Settings for any instance of the AGNS folder including the “All Users” folder
*** We have found instances where AGNS existed under other computer names such as Administrator, so please ensure all AGNS folders have been deleted.

After this is completed close out Windows Explorer

 

6. Go to Start, run and type in regedit and click ok.
Delete the following keys if present:

HKey Local Machine -] Software -] AGNS
HKey Local Machine -] System -] Current Control Set -] ENUM -] ROOT -] ATT_AGNFILTMP  or Anything that begins with ATT_
HKey Local Machine -] System -] Current Control Set -] ENUM -] ROOT -] ATT_AVPNNIC

HKey Current User -] Software -] AGNS 

*** If any registry key cannot be deleted, right click on the key and select permissions.  Check the full control option under ALLOW then click OK. Retry deleting the

Close regedit

 

7. REBOOT your workstation.

Re: Unable to install/repair/uninstall AT&T Net Client 7.0.2

I checked the screenshot you sent and the AGN Filter interface and AT&T Wi-Fi Support Driver are not present any more.

They were removed during the uninstall process which should happen.    In some circumstances, it doesn't and that why we have you check.   I would move on to sStep 3.

 

 

Thank you.

Since it is not allowing you to remove it manually try Step 4  the Windows Installer Clean-Up Utility.  

Let me know if that removes it.

 

Thanks.
