In C:\Program Files\Microsoft SQL Server*nnn*\Setup Bootstrap\Log there is a folder for each installation attempt you have made. The files of most interest are summary.txt and details.txt, although I'm uncertain what exactly is available when Setup fails during rule-checking. In any case, we need to see the log files you have to get more information about what is going wrong.

In the path above, nnn is a number that depends on which version of SQL Server you are trying to install. For SQL 2022, it is 160.

To anyone who has the same problem and isn't the most computer savvy, try the steps below. I've tried every other suggestion and nothing has worked, so I turned to ChatGPT for some help (as a last straw because it usually ends up frustrating me more with all the additional errors that arise with code from there), and it actually worked! Just opened the command prompt and typed out the code and tried the install again. Hope this helps.

Open an Elevated Command Prompt:

Right-click on the Start button (or press Win + X) and select "Command Prompt (Admin)" or "Windows Terminal (Admin)" to open Command Prompt with administrative privileges.

Change Directory to WMI Folder:

In the Command Prompt window, type the following command and press Enter:
cd

This command changes the current directory to the WMI folder where the necessary files are located.

Grant Permissions to WMI Namespace:

After changing to the correct directory, run the following command to grant the current user account permissions to the WMI namespace:
for

This command compiles all .mof and .mfl files in the directory, which effectively grants the necessary permissions to interact with the WMI repository.

Salvage and Reset WMI Repository:

After granting permissions, attempt to salvage the WMI repository by running:
winmgmt /salvagerepository

If successful, follow up with resetting the WMI repository:
winmgmt /resetrepository

Verify and Continue Installation:

After resetting the WMI repository, try to verify the repository again:
winmgmt /verifyrepository

Ensure that there are no more access denied errors.

Proceed with SQL Server Installation:

Once the WMI repository issue is resolved, attempt to install SQL Server 2022 Express Edition again. Hopefully, the "Invalid class" error during installation should no longer occur.

Hi ,

I had the same issue.

Just try uninstalling every SQL related things from your system. I had Oracle and MySQL Workbench. I deleted all of the connector files, and the SQL and Oracle application.
Also remove its folder from Program Files.
Additionally delete the registry (WIN+R and search regedit)
Delete the files connected with Microsoft SQL Server under HKEY_CURRENT_USER—Software—-Microsoft. Delete the files connected with SQL under HKEY_LOCAL_MACHINE—SOFTWARE—Microsoft .
Then reinstall MS server 2022.

This worked for me.

Good luck !
