[SOLVED] Cannot install Bitlocker Feature on Server 2019

[Warmonger666]

Using Server Manager to add Bitlocker Drive Encryption feature and getting the following error:
"The request to add or remove features on the specified server failed. Installation of one or more roles, role services, or features failed. The reference assembly could not be found. Error:0x80073701"

I have run suggested DISM commands and SFCFix but problem persists. Please see attached CBS.LOB. Thanks in advance for any help.

Hello @Warmonger666 ,

If you are still needing help with this it looks to be because of references to a cumulative preview update (KB4598296) which I suspect is no longer on your system.

Step 1:

We can check which updates are on your system by the following:

Open a command prompt (cmd)
Type: systeminfo

Copy and paste the text from the section on Hotfixes into your next post. It will be a list of KB numbers installed on your system.

Step 2:

In anticipation that we will need to remove certain registry references we can search for them as follows:

FRST Registry Search
1. Click your Start button and type in cmd.
2.After you find the Command Prompt, right click on it and select Run as Administrator.
3. Copy and paste the following into the Command Prompt:

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

4. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
5. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
6. Copy and paste kb4598296 into the Search box and click the Search Registry button.
7. When the scan is complete a notepad window will open with the results. Please attach this to your next reply. It is saved on your desktop named SearchReg.txt.

Thank you for taking the time to answer this. But a suggestion from another user to do a "update-in-place" of
Server 2019 Standard fixed the problem.

That is good to know! I'll mark this as solved and hopefully your solution will help someone else!
