Hi Narcisse,

Thank you for choosing Windows 8 as your operating system.

I see that you receive the error code: 0X80073CF9, and are unable to install apps from Windows Store.

Let us work together to resolve this issue.

I would like to inform you that this error code is usually related to a folder that’s missing and prevents apps from installing.

Method 1: Recreate the AUInstallAgent folder.

**a.**Press Windows key + R to open the Run Dialog.

**b.**Type %windir% and press Enter. You should now be in the Windows folder.

**c.**Look for a folder called AUInstallAgent. If it is missing in the Windows folder, then right click on an empty space and click on New folder.

**d.**Rename the folder as AUInstallAgent.

**e.**Restart the Computer and check if you are able to install apps.

If the AUInstallAgent folder is already available in the above mentioned location, then continue with these steps

Method 2: Reset Windows Store Cache.

Follow these steps to do so.

**a.**On the desktop, press Windows key + R to open the Run Dialog.

**b.**Type wsreset.exe and press Enter.

Method 3: Try to install the apps in Clean Boot.

To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts**.**Here is the link for your reference to perform clean boot.

http://support.microsoft.com/kb/929135

**Note:**Please go through the section: How to reset the computer to start as usual after troubleshooting with clean boot of the KB article to boot the computer in normal startup after fixing the issue.

Check if you are able to install or update the apps in Windows Store.

Please get back to us with the results.

I know what the problem you're having is. Your Store app is unable to write data in C:\ProgramData\Microsoft\Windows\AppRepository\Packages, so you can not download any apps from the store

Here is how to fix it:

+)First, you need to take ownership the folder AppRepository on C:\ProgramData\Microsoft\Windows\AppRepository. (If you don't have the folder ProgramData, go to Folder Options, check the Show hidden files and folders option). You download the Take Ownership registry here http://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/ and follow the instruction on that site to take ownership of that folder.

+)Second, you need to give the SYSTEM account and the ALL APPLICATION PACKAGES account full control on the folder C:\ProgramData\Microsoft\Windows\AppRepository\Packages. Here's how you do it
- Right-click on the Packages folder and select Properties.
- Go to the Security tab and click Advanced.
- In the Advanced Security Settings, click the Add button
- Click on the "Select a principal" link located at the top of the window
- Type "ALL APPLICATION PACKAGES" (without quotes) in the textbox of the new window and click OK.
- Check the following permission Full control, Then click OK
- And do the same with SYSTEM account****

It works perfectly for me. I also tried every solotions on the internet but none of them worked. It turned out to be very simple, the Store app is unable to write data on the installation folder. Let me know if it works for you

Do not try method one I repeat do not try method one.

Doing so,Will crash computer and force it to repair itself. Deleting all your files and signing you in forcefully in a temporary account. All my files are gone, for that i thank this stupid person.
