Error code 80073cf9 when installing my own app from Store

Question

I get the error code 80073cf9 when I try to install an 8.1 app (.appx) from the Store on my 920 with 8.1 Preview.

The app is 8.1 only and I'm able to run it and install it when deploying from my laptop.

I have the development build installed on my phone.

Solution

Uninstall the development build from your phone and then you will be able to download the app from Store.

Some interesting facts

Since 8.1 (.appx) you can not install an app from Store if you already have the app installed. This include your development builds deployed from your computer.

Before 8.1 (.xap) you were able to run both your development build and the Store app at the same time. This was since the Store changed the GUID of the app when it was uploaded. For some reason Store doesn't change the GUID of the uploaded app anymore.

This is actually wrong. If the GUID is different, nothing prevents you from downloading the same app with another GUID. – Claus Jørgensen Apr 29 '14 at 14:39
So I need to manually alter the GUID before I publish the app? – Mikael Dúi Bolinder Apr 29 '14 at 19:11
No, the store changes the GUID itself. – Claus Jørgensen Apr 29 '14 at 20:10
It did with the .xap's, but it seems to forget to do it with the new .appx's – Mikael Dúi Bolinder Apr 29 '14 at 20:12

Clarify your answer to say it's specific to Univeral Apps (.appx), and I'll exchange my downvote for a upvote! I wasn't aware the Store team had cocked it up for .appx. (I'll make sure to yell at them next time I'm in Redmond) – Claus Jørgensen Apr 29 '14 at 22:09

I also meet the error 80073CF9. With my case, the reason is the setting of memory location. I reproduced the issue as below: 1. I chose phone memory to install apps 2. Second, I updated the phone from Windows 8.1 to Windows 10. Somehow, I changed to SD card memory to install apps. 3. After upgrading to Windows 10, some apps had to be reinstalled, but the error 80073CF9 raised. At that moment, the phone still used SD card memory to install apps, not the same as the original memory. --> I switch the memory to install apps from SD card to phone (Setting / Storage / Store new apps on my Phone. It's done.

Conclusion with my case: The memory in order to install application has been changed
