This app wasn't installed error 0x80073cf9

I have the same problem. I cannot install any application from the Windows Store, having always the same error: "This app wasn't installed...", and then it points to error code "0x80073cf9". I see that a lot of people have the same problem. It looks like a bug in the new Windows 8. I have Windows 8 Pro. I just installed yesterday.


I would appreciate any help.


Look if the folder "AUInstallAgent" is missing from the windows folder. If it is, you will need to create a new folder, rename it as "AUInstallAgent"  and reboot your pc.

I just wanted to update this to add that I had the same problem in Windows 8.1 and the solution there was to create the directory "C:\Windows\AppReadiness" which apparently replaces the "AUInstallAgent" directory from Windows 8.

Why the store can't just create the directory if it's missing a real mystery....
