Re: Error 1720 Can't reinstall AT&T Global network client

Please follow the manual removal steps to uninstall the Global Network Client. 

 

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.Run the Microsoft Fix it tool

4. 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 5.

 

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.

After this is completed close out Windows Explorer

Re: Error 1720 Can't reinstall AT&T Global network client

I see the following error in the install log.

 

There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor. GetTempFileName Custom action script error -2146827859, Microsoft VBScript error at runtime: ActiveX component can not create object

 

SSCRIPT_VERSION_MISSING = The InstallScript processor is not in the computer. If available, run ISScript.msi or contact your support personnel for assistance.

 

 

********

Go to Start, control panel, administrative tools, and then Services.   Look for Windows installer and make sure it is not disabled.


If the error still occurs  and you have already tried the manual uninstall procedures and running the microsoft fix it tool outlined above, you may want to try repairing msiexec.
Please refer to the microsoft article:
