Error code 80073cf9 when installing my own app from Store - windows-phone-8.1

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.

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

I had the same problem on my Lumia 730.
Solution: Go to settings->Tap on storage sense->temporary files-> delete

The project needs to be deployed before it can be started

Whenever I am starting to test an Windows Phone app (even a blank app) on emulator, I am getting error "The project needs to be deployed before it can be started". The emulator will be started & run successfully, still no luck in deploying app on emulator. Getting error DEP6100 & DEP6200.
These are the stuffs I tried till now:
Checked "deploy" option in 'Configuration Manager'.
Tried deploying Windows 10 Mobile, Windows Phone 8.1 & Windows Phone 8 blank apps on different types of emulators.
Although I am able to run apps on my device.
I am running Visual Studio Enterprise 2015 on Windows 10 Enterprise.
The Emulator is x86 based and Phone is ARM architecture. To run the app in the emulator, change the CPU to x86 in the toolbar and compile it. Now you can deploy te App to the Emulator and test it.
I faced problem like that and I fixed it by right click on project > properties > change platform target to X86.
I just started playing with Xamarin Forms, and ran into this error after following the Xamarin Forms Quickstart Guide. The error message actually said to Run the Deploy... for the project that you are trying to run. Deploying the project seems to install some Windows dependencies that might be required to run the UMP. After deploying the project, it ran without issue as a Windows Desktop app, or if you change to Device, then install emulator, as Windows Phone app.
This error was relentlessly happening to me as well, and I found out that it was because my project was saved on a SanDisk SD card. If I simply moved the entire solution to my C drive, it built without issue, but on the D drive, it would give this error.

Publish windows phone 8 silverlight app

I am having windows phone 8 silverlight app. I need to publish it on Windows store. Can you please provide or explain step by step guide to publish this app in store.
Stackoverflow link discussed already. But after changing the values in files manually what need to do after tha?
I followed the steps mention here, but i am getting certification issue after submitting app.
This is a guide to publishing applications in Windows Store. Important -Silverligth app supported only Windows Phone and not supported Windows 8 and Windows 10. For supported Windows RT you need to make migration to universal app.
Windows App certification kit is very nice utility. Before publishing app use this app for analysis. When i run analysis of my XAP file using this utility, I found that i was using some default images that was main issue in certification failure. Now i am updating that. And will let you if this works or not.

Windows Phone Emulator 8 can't install Xamarin application

I have created a Xamarin application and compiled to Release. It was succesfully tested on an Android emulator so I decided to deploy it to a Windows Phone 8.0 Emulator.
I tried to use the Application Deployment but it cannot install because it starts the emulator that never boots, it shows OS starting (starting the emulator on its own is working).
So I downloaded it to the phone and when I try to open it, it says:
Can't install company app. There is a problem with this company app.
Contact your company's support person for help.
Why is the app considered company app? How can I install it to the emulator? What should I set?
The solution consists of two steps.
The company app issue is present because I've downloaded the application from a website, so it is unsafe (the source is the Internet). I have to install it through application deployment (via Visual Studio 2013 or the Windows Phone Application Deployment application).
The second step is to discard (and uninstall) Windows Phone 8.0 and change to Windows Phone 8.1. That helps a lot.

Windows phone xap testing and sharing

I'm developping an application with Cordova targeted for Windows phone 8.
I'm able to build a De bug or Release Xap for windows phone and deploy it on device using usual tools. The matter is that my clients want to test it too but they don't have any of sdk tools (only a device).
What is the better solution to do that ?
Installing Xap file from sd card or phone storage doesn't work (company issue message). Sign xap with sdk tools for testing and then retry to install it from sdcard doesn't work.
Is the beta test store the only solution ? (Very long procedure)
Ty fort any tips...
The easiest way is just to create a beta and send them a download link. It's done in less then 5 minutes and you can update the app quickly, publish it again and retest it within minutes.

Windows phone 8.1 app deployment error :Error-package failed updates, dependency or conflict validation

This is what exactly is did:
Installed windows phone 8.0 SDK.
Installed windows phone 8.1 SDK(By first installing VS 2013 professional edition and later installing update R2).
After that 8.1 application xap deployment is failing
Unable to deploy xap on windows 8.1 phone using 8.1 deployment tool “Error-package failed updates, dependency or conflict validation”
The phone i am using is 8.1 updated
Can you please let me know if iam missing something?
Thanks in advance
Using Windows Phone Application Deployment (8.1), I just ran into same issue. I had tried to install an appx package which was built for Store in Release Mode.
I then realised I was trying to install an ARM build onto the emulator which needs an x86 build to run.
So instead I deployed the ARM Release Mode .appx to a physical device so I could test what I needed to test.
Hope this helps!
Not a real answer but an un-explained work around. I've recently started developing against windows phone. I am working on a Windows 8.1 machine that was previously a Windows 8 machine, previously using VS 2012 to develop against WP 8 and now using VS 2013 to develop for WP 8.1.
At intervals I start to receive the same error as reported by the question, both when deploying our WP 8.1 app to an emulator and when trying to run or debug our WP 8.1 unit tests. So far it's been resolved each time by restarting VS 2013 (and the emulator). Restarting the emulator alone has sometimes been sufficient but not always. I have not checked whether it works against a concrete device. More significantly I have no idea why deployment breaks or stopping/starting resolves it...
Our application and unit tests are WP 8.1 silver light projects and use SQLite.
