All we need is an easy explanation of the problem, so here it is.
On my Windows 8 desktop I keep getting error 0x80073cf9 when I try to install or update an app from the windows store.
In the installings apps pane it just says “This app wasn’t installed — view details” and when I select that it says “Something happened and this app couldn’t be installed. Please try again. Error code: 0x80073cf9”
I am using the built-in windows firewall and antivirus. And my laptop is able to install updates when it is on the same network.
This is what winstore.log shows when I try to update the maps app:

How to solve :
I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.
Not sure how it could have happened, but this seems to be a possible solution:
The problem is that the folder AUInstallAgent is missing from the Windows folder.
I had this problem, recreated the folder and low and behold all is working fine.
Now what I want to know is why the folder disappeared in the first place, because I didn’t delete it, and looking around the web I’m not alone….
This solved it for me.
(I have tried all the mentioned solutions and none of them worked for me.
I also tried to run WSReset, uninstall and re-install, nothing wanted to work.
I was about to format and reload my PC, when I found one last suggestion to try and it sorted out the problem!)
First I do not want to take credit for this!
The hint was given by “Alex from the ’90s”, as solution for a download problem of Asphalt 9.
ERROR 0x80073CF9 nagged me for over a year now. All store repair procedures failed, ending with the reinstall all suggestion.
Now here the solution. Take care modifying registry values!
It’s value has to be set to ZERO.
Apparently the Microsoft Store wants to make use of partial file encryption, possibly for license protection reasons.
If you have that value set to 1 accidently (maybe with a modding tool), that procedure simply fails. 0x80073CF9 is maybe not the best code to indicate that.
I tried almost everything to no avail. Then I added a new user (with administration rights) from with in the control panel.
If you go to Users Accounts in the Control Panel, click manage accounts then find the add accounts link. After you have added the account with a different name, hit Ctrl Alt Del, select SIGN OUT, then sign in as the new user, all the app stuff now works, try it out.
All your programs are there, if not on the desktop, you can add a shortcut link on the desktop. The next step is to delete the old and worthless user. Done. You can rename the new user from the control panel.
Try creating the folder

After looking on the internet for hours, I found this command in a youtube video from about 3 years ago.
Put the following command in you CMD and you will be fine:
fsutil behavior set DisableEncryption 0
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
