[SOLVED] Cannot install .NET features on Windows server 2019

[skharlamov]

Hello, when trying to install .NET features using
Install-WindowsFeature NET-Framework-45-Features
it gives error
Install-WindowsFeature : The request to add or remove features on the specified server failed.
Installation of one or more roles, role services, or features failed.
The referenced assembly could not be found. Error: 0x80073701
According to CBS logs Failed to pin deployment while resolving Update: Package_3710_for_KB5004244~31bf3856ad364e35~amd64~~10.0.1.7.5004244-6910_neutral from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]
This KB does not exist in Microsoft update catalog.
So I ran Farbar recovery scan tool with limit KB5004244 in search registry. Please find attached search results and CBS logs.

Hi,

Follow these instructions first to try remove this 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:5004244

• Let me know if it says it was successful or you get the message: The update KB5004244 is not installed on this computer.

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 FRST64.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 try to install the .NET features, when it fails attach a new copy of the CBS logs.
