Uninstall SQL Server Components Continue

This is in continuation of Completely Uninstall SQL Server Components article. If you have not read that please click on the above like and then comeback to this page.

If msiinv.exe as mentioned in the first page works fine then it is good for you. Run the command once again and verify the output file.

PS C:\msiinv> .\msiinv.exe -s | Select-String "SQL Server" -Context 1,1 > C:\msiinv\msiinv_result2.txt

This time there should not be any SQL Components which you removed. If you see the components that means even msiinv.exe did not work. What is next?

You need to use Windows Installer CleanUp Utility. It is developed by Microsoft for Windows OS to resolve uninstallation problems of programs that use the Windows Installer technology. It wipes Invalid or corrupted entries from registry for the component.

There are many links available in the internet to download the tool. You can directly get it from here as well Windows CleanUp Utility

The utility displays a list of all the Windows Installer-based applications on the system as shown below:

Uninstall SQL Server

Select the component you want to uninstall and click on Remove:

Uninstall SQL Server

Note: Never Ever click on Select All. Tools are good until you make a mistake.

Completely Uninstall SQL Server Components

In this article I am going to show you how to Completely Uninstall SQL Server Components which are left behind. In other words what to do if the regular uninstall process from Control Panel fails.
Even more, sometimes the control panel shows that the SQL component has been uninstalled. But when you try to reinstall, it fails again. And this is because of the left behind components.

There are many articles in the internet suggests to change registry entry. Modifying registry is always associated with risk. For me it didn’t work, may be because the registry was corrupted.

You need to use the MSI inventory tools to check and uninstall the components. I have made it available for you in the following link  Download msiinv.zip

The original source is Download from One Drive

Once downloaded open Powershell and run the below command. In the below example I have downloaded the msiinv in D drive under msiinv folder. Please put valid paths and then run the command. This will create the out put file with all the GUID of the SQL Components.

PS D:\msiinv> .\msiinv.exe -s | Select-String "SQL Server" -Context 1,1 > D:\msiinv\msiinv_result1.txt

If the execution is successful it will go to the prompt again as shown below:

Uninstall SQL Server

The result set will look like as below:

Uninstall SQL Server

You can find out the components you want to remove and note the product code from the file.
Execute the below command in PowerShell to uninstall the component.

 msiexec /x "{6BD8D100-B16C-409E-B0EA-BF508D7874EC}"
This will ask for final confirmation:

Uninstall SQL Server

If you are not comfortable with PowerShell or facing issues, then you can use command prompt to use the msiinv tool as shown below:

Command to execute is as follows:
msiinv.exe -p > D:\msiinv\msiinv_result1.txt

Uninstall SQL Server

The output file will have all the Windows components and not only SQL Server. You have to search through the file for SQL Server and use the same command as shown above to Uninstall SQL Server.

Sample file:

Uninstall SQL Server
