Sharepoint server 2016 prerequisite installer failing with error re unable to download Microsoft App Fabric

Question

We are trying to run the Microsoft Sharepoint 2016 products preparation tool ( prerequisiteinstaller.exe that comes with the Sharepoint 2016 iso file ( Officeserver.img )

We are doing an offline install.

We have installed all the prereqs - includiing WindowsServerAppFabricSetup_x64.exe and AppFabric-KB3092423-ENU.exe

We are using serv3er 2019 (standard).

When we run the prerequisiteinstaller.exe it still says

"Windows server AppFabric: Download error" - which seems to indicate that it cannot detect that AppFabric is already installed and is trying to download it.

The log file says

2023-02-20 17:47:18 - Check whether the following prerequisite is installed:

2023-02-20 17:47:18 - Windows Server AppFabric

2023-02-20 17:47:18 - Reading the following string value/name...

2023-02-20 17:47:18 - ProductVersion

the DWORD DCS is not present at this place in the registry. Only the following DWORDS are present

Name Data

Default - (Values not set)

DCC (1)

Worker (1)

WoderAdmin (1)

i.e. no DCS DWORD.

the log file does not say its already installed, and the next lines in the log are:

2023-02-20 17:47:18 - Check whether the following prerequisite is installed:

2023-02-20 17:47:18 - Microsoft Identity Extensions

... and then later

2023-02-20 17:47:18 - Check whether the following prerequisite is installed:

2023-02-20 17:47:18 - Cumulative Update Package 7 for Microsoft AppFabric 1.1 for Windows Server (KB3092423)

2023-02-20 17:47:18 - Reading the following DWORD value/name...

2023-02-20 17:47:18 - IsInstalled

2023-02-20 17:47:18 - from the following registry location...

2023-02-20 17:47:18 - SOFTWARE\Wow6432Node\Microsoft\Updates\AppFabric 1.1 for Windows Server\KB3092423

2023-02-20 17:47:18 - The value is (1)

2023-02-20 17:47:18 - The prerequisite above is already installed

So why is the prereqinstaller still trying to download appfabric when its already installed ?

Also - we seem to have Appfabric 1.0 installed - but think we shoud be using appfabric 1.1

Hi @Greg Booth ,

There could be many reasons for this problem. But most common problems due to manual installation and having incorrect system variable for the PowerShell path

To resolve this Just uninstall the existing installation from the control panel and re-run the SharePoint prerequisites installer or Auto SP Installer. Reference :
