Answer 1

Hello,

The error code 0x80073701 indicates that a referenced assembly could not be found, which often points to missing or corrupted system files. Here are some steps you can take to resolve this issue:

1.Run the System File Checker (SFC) Tool:

Open Command Prompt as an administrator.

Run the following command:

sfc /scannow

This will scan and repair any corrupted system files.

2.Run DISM Tool:

Type cmd in the Windows Start Search box.

Right-click on the Command Prompt and go with the option Run as administrator.

Now, enter the below command,

dism /online /cleanup-image /startcomponentcleanup

Nextly, restart your computer to take effect and check if the issue is resolved and whether you can install IIS features on the windows server or not.

3.Check for Windows Updates:

Go to Settings > Update & Security > Windows Update and check for updates.

Install any available updates and restart your server.

If the issue started after a recent update, consider uninstalling the update.

Go to Control Panel > Programs > Programs and Features > View installed updates and uninstall the problematic update.

4.Check Logs and Remove Patches:

You will have to check the CBS.log and remove the patches in this method to resolve the error 0x80073701.

The CBS.log is a file that includes logs about components when they get installed or uninstalled during updates.

The CBS.log file is located in the %windir%\Logs\CBS folder.

If you find any error, then re-install a particular file.

But, If there is no error in the CBS.log, you must execute the below command,

DISM /Online /Cleanup-Image /ScanHealth

This command can check for component store corruption. Hence when the command completes successfully, you will be able to install the IIS feature on your Windows Server.

I hope the above fixes help you resolve the error 0x80073701, and you can install IIS features to your Server.
