Windows Update Error 0x80246001

[German]Occasionally, Windows users are facing an update error 0x80246001 and the update install process aborts. This can occur on Windows 7 to Windows 10, but also on Microsoft Office. Here is some information about this error.


A brief error description

I recently came across the problem with Windows update error 0x80246001 within this comment here in the blog. The user writes:

Hello, [I] have here several failed update KB4474419 installation at the in Win7 x64 Pro.
Code: 0x80246001 (Download failed)

One possible cause, a missing Servicing Stack Update (SSU), can be excluded according to this error description. 

However, the update error occurred many years ago, when SSUs were not yet an issue. I found the first hit from 2005 during a short search for a Windows XP update. Another post from the Microsoft Answers forum is from 2015 and refers to Windows 10.

What does update error 0x80246001 stands for?

For error diagnosis it is helpful to decode the error code as accurately as possible. The specification 'Download failed' in the description above is not very helpful. I have listed the known or documented 0x8024xxxx update errors in the blog post Windows 10: Update errors 0x8024xxxx detailed.


Update error code 0x80246001 stands for WU_E_DM_URLNOTAVAILABLE and there is the explanation: 'A download manager operation could not be completed because the requested file does not have a URL'. In plain text: There is an update request, but it simply does not contain a URL to download the requested file from the Microsoft update servers.

Problem solving approaches

In order to address the problem in a structured way during the update installation, it is advisable to go through various possible solutions. I have put together some approaches here that you can try.

Fix #1: Download and install update manually

In a first step, I would try to download the relevant update from the Microsoft Update Catalog using a browser. Simply search for the KB number on the page and then select the appropriate update package to download.

Afterwards you can select this as an administrator by double clicking on it, to start an for installation. It is possible that the update will be installed successfully. Otherwise it is possible that manifest files have an incorrect reference and cause the installation error. Then the following diagnostic steps should be carried out..

Fix #2: Check, if foreign virus scanner is the root cause

Not Windows compatible foreign virus scanners can damage Downloads in such a way that the several errors may occurs. In order to exclude this source of error, installed third-party virus scanners should at least be deactivated for testing purposes. But this is often not enough – then I would uninstall the external virus scanner for testing purposes and then run a Clean Tool from the AV provider to clean the system of installation remnants. If the AV suite is not the cause of the malfunction, you can reinstall it after a successful diagnosis.

Fix #3: Check Windows for damages

Damaged Windows system files can also lead to the most impossible errors. As a precaution, and to eliminate this source of error, the system should be scanned for corrupted files. The exact procedure depends on the version of Windows. In Windows 7, sfc /scannow and the CheckSUR tool can be used. See this KB article and System Update Readiness Tool for Windows 7 (KB947821) for details.

From Windows 8 to Windows 10 it is necessary to check the system with sfc /scannow for damaged files. The component store can then be checked for errors using dism. These approaches are described in the blog post Check and repair Windows system files and component store. Both methods try to repair detected damages at the same time. With a little luck, it also fixes the update error.

Fix #4: Reset Windows Update Components

Windows stores information about downloaded and installed updates in a component store. Damage in this area can lead to misreferences to non-existent files. Checking the component store with dism should be able to repair some things. But a broken download might not be fixed.

Therefore it is recommended to reset the Windows Update components. There is an update troubleshooter for different versions of Windows for this purpose. But this rarely helps. Therefore I would try the reset manually.

To do this, stop services and then delete certain files. One approach is described in this Microsoft Answers forum article. There qmgr*.dat is deleted from the user profile. In a further step the download folder for updates and the folder DataStore as well as the folder catroot2 can be deleted manually. More details can be found in this Microsoft support article. I also explained the steps to delete certain folders in more detail in the blog post Windows Update Error 0x8007042B.

Didn't help?

You should also check your internet connection. Below are some linked articles on the diagnosis of update errors. Maybe some of the approaches mentioned here will help.

Finally, a warning: If you search for the error code, you will also find result pages that offer the download of a repair tool. Such solutions should not be used for security reasons. Nobody knows what is being done to you, and maybe it won't work either. If then a chargeable download was transacted, the annoyance is large. Also the offered help sides with Chat function should avoid concerning.
