• 0xC1900209 0x4000D

And honestly speaking, the two aren’t very helpful in identifying what’s causing it.

Don’t worry! We have got you covered. Go through the following sections to find the underlying cause and the solutions for the 0xC1900209 update/upgrade error.

What is error code 0xc1900209?

The error code is usually encountered due to incompatibility issues concerning the installed apps or drivers. For example, if the app installed on the current version/iteration is incompatible with the one you are updating/upgrading to, the 0xC1900209 error would show up.

Also, specific background applications, including third-party antiviruses, though compatible with the OS, are often found to conflict with the update/upgrade process and lead to this error.

No matter the underlying cause, the 0xC1900209 error can be fixed easily with the solutions listed in the next section.

How do I fix error code 0xc1900209?

1. Use third-party software to fix the error

Windows Update issues are incredibly diverse, and sometimes it’s impossible to pinpoint the cause of the error.

That means that the troubleshooting soon becomes time-consuming and tedious. Luckily, in this case, you have our guide to indicate exactly what you need to do, but even so, the manual process can be tricky for most.

However, a quicker and easier way to fix this problem is by using a dedicated third-party solution that can automatically clear the issue.

2. Use the Windows Assessment and Development Kit (ADK)

2.1 Download and install SQL Server

1. Download Microsoft SQL Server from Microsoft’s website. The ADK will use a SQL Server database to store its entries, so you can’t go further without installing this.
2. Open the SQL Server installer.
3. The installer gives you three options to install SQL Server. First, the easiest and fastest way is to go with Basic, so choose that and follow the on-screen instructions to complete the process. The 0xC1900209 0x4000D error will be fixed afterward.

2.2 Download and install the ADK

1. Download the ADK installer.
2. Open the ADK installer. Click Next in the first two windows and agree to the terms of the License Agreement on the third.
3. Select the features you want to install window, select Application Compatibility Tools, uncheck everything else, and then click on Install at the bottom.
4. Wait for the installation to finish.

You are ready to install the Windows Assessment and Development Kit to find and fix any compatibility issues causing the 0xc1900209 error.

2.3 Use the ADK to detect compatibility issues and fix them

1. Launch the Compatibility Administrator application.
2. Click on Search in the menu bar and choose Fixed Programs… from the list.
3. Click on the Find Now button and wait until the application has finished the search. This goes through the folder where your programs are stored and matches them against the database of a known application list with compatibility issues. In the end, the program will come up with a list of applications in the bottom pane.
4. Double-click on an item from the list.
5. It will take you back to the program’s main section with an entry selected. Right-click on the desired item and copy it.
6. Please go through the list until you find an entry titled New Database under Custom Databases, right-click on it, and paste the copied entry.
7. Repeat steps 4-7 for each item on the list.

NOTE

Only if you have a 64-bit Windows: In your version of Windows, programs are not only stored in the Program Files folder but also the Program Files (x86) folder. That’s why you must also search for compatibility issues there. Click on Browse in the top right corner, select the Program Files (x86) folder, and repeat steps 3-8 again for this folder.

Once done with the Compatibility Administrator, the 0xc1900209 update error will be fixed, and you can install the desired version/iteration of the OS.

3. Update the installed drivers

1. Press Windows + S to open the Search menu, enter Device Manager in the text field, and click on the relevant search result.
2. Double-click on the Display adapters entry.
3. Right-click on the graphics adapter, and then select Update driver.
4. Now, select Search automatically for drivers.
5. Wait for Windows to automatically locate and install the best available driver on the computer.

In some cases, Windows might be unable to locate a newer version while one is available. So, you should also try manually updating the drivers installed on the computer. Remember to update all the drivers.
