SharePoint 2013 Pre-requisites installation failed with error "Windows Server AppFabric: installation error"

After checking event logs, below error is logged.

"AppFabric installation failed because installer MSI returned with error code : 1605"

I have tried to install it manually using below command but it failed with same error.

prerequisiteinstaller.exe /AppFabric:prerequisiteinstallerfiles\AppFabric1.1-RTM-KB2671763-x64-ENU.exe

Also checked the environment variable value and it is as below.

C:\Windows\system32\WindowsPowerShell\v1.0\Modules\;C:\Program Files (x86)\Microsoft SQL Server\110\Tools\PowerShell\Modules\;c:\Program Files\AppFabric 1.1 for Windows Server\PowershellModules

Even as suggested in few blogs checked for the groups AS_Observers and AS_Administrators and these groups does not exist.

Can someone suggest any other solution???

  • I had the same problem as OP. Spent days trying to find a fix. I tried uninstalling and reinstalling AppFabric via command line. It did not work for me. I then tried the PSModulePath solution that's been suggested everywhere. Did not work for me. At one point I realised I couldn't even install AppFabric at all (error code 1603) so I couldn't uninstall it either which is why a lot of the fixes weren't working. I must have stuffed something up from one of the fixes I found online. I don't know if that was your issue, but ultimately I started the installation from scratch again. It was faster.

Before running AppFabric1.1-RTM-KB2671763-x64-ENU.exe, you should make sure that you have installed WindowsServerAppFabricSetup_x64.exe as the following:

  • Open CMD as administrator,

  • Navigate to the folder that contains WindowsServerAppFabricSetup_x64.exe (In my example I consider it in C:\ drive)

  • Run the following command

.\WindowsServerAppFabricSetup_x64.exe /i /gac

  • Now Click on AppFabric1.1-RTM-KB2671763-x64-ENU.exe to install the AppFabric patch.
  • Reboot the server > Run SharePoint Installation again where the message error should not be listed again.

For more details check Windows Server AppFabric is not correctly configured During installing SharePoint Server 2013

  • I tried the steps suggested by you but still same error(AppFabric installation failed because installer MSI returned with error code : 1605) while running SharePoint Installation after reboot. Feb 14, 2017 at 5:14
