How to fix Windows Store app install error 0x80073CF0 in Windows 10

As much as I love Windows 10 and its Windows Store over the past year or so I have found the Store can suffer the odd technical issue. Once issue I have come across that can be a real pain is when an app update fails, often with the cryptic error code 0x80073CF0. The error means that the Windows Store has failed to download the update and it has an invalid cache of the app. Normally this is caused by the internet dropping during the app update.

I hunted around for solution and found some contradictory solutions and some instruction that where plain wrong (the Microsoft Answers forum seems to the be worse place!).  In the end I worked out a solution so I thought I would document it in case anybody else has the problem.

The root cause of the problem is that Windows stores app downloads in the C:\Windows\SoftwareDistribution\DeliveryOptimization folder and in this case the app has only part downloaded and the file is invalid, re-trying download from the Store fails as it uses the cached file so you get the 0x80073CF0 error.

The solution is to delete the cached file. You can’t do that normally as the Windows Store locks the files so I found the best way is to reboot the PC and then after the reboot delete the DeliveryOptimization folder. Once you have done that you can reinstall the app in the Windows Store.

This worked for me and hopefully it will work for you.

  • If you don’t have enabled “Updates from more than one place” in Settings, the folder is C:WindowsSoftwareDistributionDeliveryOptimizatioDownload”

      Actually is C:WindowsSoftwareDistributionDownload. In the “DeliveryOptimization” folder was no sub-folder so what I did (since deleting the whole folder didn’t work for me), was to go to “Download” folder, sorted the content by the date and deleted the folder that showed current date/time (that means it was the one with the broken download). After that tried updating/downloading the app again from Store and worked fine
