How to install Application Initialization Role

Question

I am trying to install the Application Initialization role on server 2019 standard version 1809. I already have the Web Server (IIS) feature installed and 15/43 of those features under it are installed.

When I try to just add the Application Initialization role, I get a 0x80073701 error (The reference assembly could not be found). I check the CAB log file, and see this:

Failed to pin deployment while resolving Update: Package_3308_for_KB4570333~31bf3856ad364e35~amd64~~10.0.1.7.4570333-5772_neutral from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]

I go to windows update catelog to download the KB4570333 and there is nothing that comes back when you search for that KB in the update catelog.

I have already performed the following steps in an attempt to clear out any corrupt or cached files that may have been holding this up:

Dism /online /cleanup-image /startcomponentcleanup

Dism /online /cleanup-image /restorehealth

sfc /scannow

Where do I go from here?

Answer 1

0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the update installation failure. You can also try a repair install by running setup.exe from the root of the install.

I wouldn't hold much hope for this, time may be better spent standing up a new one, patch it fully and migrate the roles or applications over to it.

Thanks for your response, @Anonymous .

Can you elaborate a bit on the "You can also try a repair install by running setup.exe from the root of the install"?

Answer 3

Honestly that is unlikely to do anything in the way of help but simply insert the windows installation disk and double-click on setup.exe in the root of the install media disk.

Hi @Cameron Beckman

I would first suggest you try getting the updates manually and see you can install them.
You can get the updates by KB (KB4570333) number from the below link
https://www.catalog.update.microsoft.com/Home.aspx

You can also temporarily disable all your antivirus and try installing the updates.

If this manual update fails you can then try using the SFC & DISM command to check for any corrupted registries and try the update installation after the restart.

Here is the link for the scan commands

If the scan yield no result then try the Inplace update which will surely sort this issue out.

Hope this resolves your Query!!
