[SOLVED] Cannot install Bitlocker role on Windows Server 2016

[Phi-]

Hi,

Basically I have the same issue as described in this thread.
[SOLVED] - Cannot install Bitlocker role on Windows Server 2016

2023-05-23 23:40:25, Error CSI 0000000a (F) HRESULT_FROM_WIN32(ERROR_SXS_ASSEMBLY_MISSING) #29056# from Windows::ServicingAPI::CCSITransaction::ICSITransaction_PinDeployment(Flags = 0, a = 8d2d4b9c18f0b29c8e9881fde76ec173, version 10.0.14393.1770, arch amd64, nonSxS, pkt {l:8 b:31bf3856ad364e35}, cb = (null), s = (null), rid = 'Package_6348_for_KB4487026~31bf3856ad364e35~amd64~~10.0.1.6.4487026-14115_neutral', rah = '2', manpath = (null), catpath = (null), ed = 0, disp = 0)[gle=0x80073701]
2023-05-23 23:40:25, Info CBS Failed to pin deployment while resolving Update: Package_6348_for_KB4487026~31bf3856ad364e35~amd64~~10.0.1.6.4487026-14115_neutral from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]

Apparently the "Package_6348_for_KB4487026" is at fault and I've tried everything from extracting the cab file and installing the package manually via dism over injecting the package into a wim file and trying to resolve it that way, over copying the package into the WinSxS folder manually (don't worry, I'm working with snapshots it virtualize onto other machines and not the production server when doing that). I'm at a loss though, since nothing helped which is why I am turning to you as a last resort. Can anybody help me?

I didn't use the farbar recovery tool yet, but only the wusa /uninstall /KB:4524152, since I've noticed you identified another KB as being at fault than the OP did.

Regards and Thank you!

Hi and welcome to Sysnative,

Follow these instructions to remove an update.

• Open the Start menu of Windows and type the command CMD
• When you see Command Prompt on the list, right-click on it and select Run as administrator.
• When command prompt opens, copy and paste the following command into it, then press enter.

wusa /uninstall /KB:4487026

• Let me know if it says it was successful or you get the message: The update KB4487026 is not installed on this computer.

Hi,

the command went through and I got the "KB4487026 is not installed on this computer", but the same error persists at the Bitlocker Feature Installation (0x80073701).

Regards

Hi,

Download the

Farbar Recovery Scan Tool and save it to your Desktop:

Download the 64 bit version: - Farbar Recovery Scan Tool Link

• Open the startmenu and type the command cmd.
• After you find the Command Prompt, right click on it and select Run as Administrator.
• Copy and paste the following into the Command Prompt and press enter.

reg load HKLM\COMPONENTS C:\WINDOWS\SYSTEM32\CONFIG\COMPONENTS

Right-click on the file FRST64.exe and choose Run as administrator.

• Copy and paste the following (code) into the Search box and click the Search Registry button.

KB4487026

• When the scan is complete, a message will display that SearchReg.txt is saved in the same folder FRST was started from.
• Post the logfile SearchReg.txt as attachment in your next reply.

Hello,

Thanks for the help. Here you go.

 

[Maxstar]

Start the

Farbar Recovery Scan Tool again.

Warning: This script was written specifically for this system. Do not run this script on another system.

• Download the attachment fixlist.txt and save it to your desktop.
• Right-click on FRST.exe and select "Run as administrator".
• Press the Fix button.
• If for some reason the tool needs a restart, please make sure you let the system restart normally.
• When finished, a log called Fixlog.txt will appear in the same directory the tool is run from.
• Post the logfile Fixlog.txt as attachment in your next reply.

Afterwards, reboot the the server and try to install the Bitlocker feature. If it fails attach a new copy of the CBS logs.

Wow, this is awesome, YOU are awesome. Thank you 100 times, that did the trick.

So if I understood correctly what happened is that I had to delete (and recreate?) all the registry values still associated with the faulty KB after its uninstall and that is what the fixlist.txt + Farbar repair script did?

Thank you very much again! You saved my day/week! I donated a little bit and will be recommending this forum wherever I can. Keep up the good work.

Hi,

You're welcome. Glad you were able to install the Bitlocker feature after removing the remnants of KB4487026. This update (Februari 2019) was not completely removed and causes this issue.
Thank you for your donation to Sysnative, I wll mark this thread as solved.
