Why is the IE 11 MSI Generated from the IEAK Failing?

Posted by William Diaz on December 8, 2014


There has been some chatter about the Internet Explorer 11 MSI that is generated from the IEAK failing while the EXE is able to run successfully. I ran into this myself last week while trying to manually execute the package. The IE11_main.log always showed the same error: “ERROR:   Error downloading prerequisite file (KB2834140): 0x800c0005 (2148270085)

After a day or so of troubleshooting I realized the problem. When the IE11 setup runs, it needs to go out to the Internet to check Microsoft for prerequisite updates; both the MSI and the EXE do this. But the MSI (msisexec.exe) executes in the context of the local system account. By default, the local system account tries to find a direct path to the Internet, but if you are behind a proxy this is going to fail as the MSI child processes (specifically ienrcore.exe) are bypassing the proxy.

The EXE on the other hand when run manually executes in the context of a user account with Internet Access. That does not mean you are entirely out of the woods with the EXE package. If you are automatically deploying and leveraging SCCM the EXE (like the MSI) is still going to executed by the local system account. To overcome this, you need to configure the local system account to use a proxy (or not use a proxy, or update your proxy). This can be done via BITSAdmin with the following command:

bitsadmin /util /setieproxy localsystem MANUAL_PROXY MyProxy:8080 "<local>"

Another workaround is to simply install the prerequisites before installing IE 11. The required KBs are:

  • KB2670838
  • KB2786081
  • KB2834140
  • KB2882822
  • KB2888049

Last, you should also be able to extract the cab files from these KBs and add them via IEAK custom components step in the IEAK. I have yet to get this to work, however, as the package still wants to go out to the Windows Update site. If you have gotten this to work, let me know how you did it.


UPDATE

I have decided to use the IE11 redistributable and avoid IEAK. Injecting updates into the package via IEAK is too much work. Fortunately for us we control everything we need to via group policy so there is no need for customizations. A script to install the prerequisite updates and then IE11 is much simpler.

Note, if you install updates then install IE11 in the same script, the IE11 installer is still going to want to go out to the Internet to check updates if you just run the executable command. There are two ways to workaround this. One is to install the updates, restart, then install IE11. But this means you have to break up your deployment into two steps. Fortunately, you can work around this. The answer lies in the IE11_main.log using DISM. When a successful install (with Internet Connection) of IE11 is completed you can find the command in the log:

Just extract the redistributable and then install IE11 via the main CAB using DISM and then the two MSUs using WUSA. For example:

::Create temp directory if not present to extract IE11 
MKDIR "C:\temp\IE11"
ECHO Installing prerequisite updates for Internet Explorer 11
"%~dp0Windows6.1-KB2670838-x64.msu" /quiet /norestart
"%~dp0Windows6.1-KB2786081-x64.msu" /quiet /norestart
"%~dp0Windows6.1-KB2834140-v2-x64.msu" /quiet /norestart
"%~dp0Windows6.1-KB2882822-x64.msu" /quiet /norestart
"%~dp0Windows6.1-KB2888049-x64.msu" /quiet /norestart
ECHO Installing Internet Explorer 11. Please wait…
::A reboot is required here, otherwise the IE11 Installer wants to still go out to Internet to check updates
::We can avoid this by using DISM instead to install IE11
"%~dp0IE11-Windows6.1-x64-en-us.exe" /X:%systemdrive%\temp\IE11
%systemroot%\system32\dism.exe /Online /Add-Package /PackagePath:%systemdrive%\temp\IE-Win7.CAB /quiet /norestart
%systemroot%\system32\wusa.exe "%systemdrive%\temp\IE11\IE-Spelling-en.MSU" /quiet /norestart
%systemroot%\system32\wusa.exe "%systemdrive%\temp\IE11\IE-Hyphenation-en.MSU" /quiet /norestart
::Cleanup 
RMDIR C:\temp\IE11 /s /q

 

Note: if you are going to be using 32bit Configuration Manager client to execute the batch file above in 64bit Windows, you will need to replace system32 paths to sysnative.
