问题:
I installed a retail version of Windows 8 Pro. I downloaded and installed Visual Studio Express 2012. I asked for and received a developers certificate. Then I tried to create a hello world app.
From there I get a "Unable to Activate Windows Store App" message box when I try to debug the app. Most commentary on the web says delete build directories. This didn't work for me
Does anyone have a solution for how to fix this and debug my app?
回答1:
This happened to me once too, but the deleting build directories advice fixed it. I assume that this is only one project since it's a Hello World app; otherwise I would ask if you deleted build directories from all projects in your solution.
You can also try running "Clean Solution" from the BUILD menu in Visual Studio.
I'm sorry...it's horrible if this is happening on a clean install as you describe.
回答2:
I ran into the same issue, and tried rebuilding, cleaning, deleting temp files, rebooting the computer, etc... and nothing helped.
Then finally I made a release build then went back to debug. And now it works.
I have no idea what happened, nor if that really helped, but it's worth a try.
回答3:
For me a RESTART of pc solved this error message.
回答4:
For me the problem was that I created the app on a TrueCrypt mounted virtual drive and when I moved the project files to a normal drive then everything worked just fine. Weird.
回答5:
I was getting the exact same error. In my case the culprit was a NuGet package. It had added an app.config file to the project and it was confusing VS. I removed the app.config file and it solved my issue.
I got the solution at Iris Classon's site.
回答6:
This can be solved by Uninstalling the app from the start screen then again building the app from Visual Studio.
回答7:
I had a similar problem, and the cause was creating the project on a USB thumb drive. Creating a project on a normal hard drive volume works.
回答8:
this can happen when the application signing key (.pfx
file) is missing.
Try the following:
- Open the
Package.appxmanifest
file in Visual Studio
- Go to the register "Packaging"
- Select [Choose Certificate…]
- Select the test certificate using [Configure Certificate…] [From File…], or create a new one using [Configure Certificate…] [Test Certificate…]
- When using a test certificate, ensure that it is in the
.gitignore
file. There should be an entry like !**\*_TemporaryKey.pfx
to include the key in Git.
- Note: The certificate for release build should only be available to the build server and not included in Git.
- Rebuild the project

The issue might be caused because NuGet will try to add an app.config with binding redirects to Windows Store apps if it thinks it is needed. However, Windows Store apps don’t need app.config, and will actually fail to start with a very confusing error message if it is present.
And the solution in this case would be to Remove the App.config
回答10:
This error generally comes when you try to deploy in debug mode.
I would suggest, deploy the app first in release mode and then try in debug mode.
This worked for me.
回答11:
Increasing the revision number of the package worked for me

This sort of problems are common with Windows 8 Visual Studio. Such errors encounters when your developer license of Visual Studio has expired so you may want to renew or get a new developer license here's how you get that. How to get a developer license in Windows 8
And similar problem may also encounter with E_Fail issues here's how to solve Unable to activate Windows Store app E_Fail Issue
回答13:
For me, the fix was a combination of two of these answers -
- Renew the developer license (How to get a developer license in Windows 8)
- And deleting the build directories (though I deleted more then the screenshot depicted) Delete the Build directories

Solution:
Remove the App.config
and build again
回答15:
This has happened to me in the past and I have always found that deleting the build directories resolves it.
However this time this is not working for me.
I have tried
- Rebooting
- Deleting build directories
- Running Build | Clean Solution in VS
- Renewing Developer Account
The only thing that will work for me is changing my Package name under the Package.appxmanifest
However I am not overly happy with this as a solution. I will keep investigating.
回答16:
For those who get a similar error but who are searching for a solution while debugging an IOT background app on a local machine specifically - you can find it here.
Using the search term "unable to activate windows store app the activation request failed with error" brought me here.
回答17:
Because of Two things i resolved this issue.
Basically, we just need to delete the bin\Debug
and bld\Debug
folders in our projects. Those contents will be regenerated by Visual Studio when you rebuild project.
Just Restart the Visual Studio. And Clean Build and Rebuild the solution and RUN it.
Hope this helps.,

Playing with this issue for 3 days, tried every suggestions, nothing works. Until now!!!
The solution was this for me:
- renew developer licence
- build and deploy solution in Release mode (after this step it still not worked, but VS installed some packages in rpi)
- start VS remote debugger with default account (http://:8080/#Debug%20settings)
- configure remote device with Universal authentication mode (VS2017 -> Project settings -> debug -> target device: remote machine, authentication mode: Universal (unencrypted protocol))
...and now I can sleep.
Hope it helps somebody.

This gift was courtesy of Microsoft's automatic updates for VS2015 which was one of the 2 culprits:
KB3022398
KB3165756
It also broke SourceTree and other apps that draw the GUI - making an outline of the app but not drawing the contents.
回答20:
For me changing the Package Name in Package.appxmanifest fixed the problem
回答21:
Making a new certificate works for me. For this, go to Package.manifest->Packaging, and follow the Choose certificate.... Click on Configure certificate and select Create test certificate. Give it a name and press OK.

In my case, the C# UWP app had a native library which failed in the application startup code, and called exit(1)
. The symptoms were identical to those in the question, though. Visual Studio would throw a message:
Unable to activate Windows Store app '88888888-6666-5555-4444-111111111111_abcdefgh!App'. The Acme.exe process started, but the activation request failed with error 'Operation not supported. Unknown error: 0x80040905'.
In addition, there was a message in the UWP app Windows log under Microsoft\Windows\Apps\Microsoft-Windows-TWinUI/Operational: event ID 5961, message:
Activation for 88888888-6666-5555-4444-111111111111_abcdefgh!App failed. Error code: Unknown HResult Error code: 0x80040905. Activation phase: COM App activation
Internally, the C# part would try to construct a native class instance from the App
constructor, the native class constructor would encounter an unrecoverable error and bail. From the UWP subsystem standpoint, and from the debugger standpoint, though, this looked as something distinct from the mere programmatic exit. I'll leave this answer here, 'cause I've spent some time chasing various UWP failure scenarios instead of running under a native debugger.
I've replaced the exit()
call with throw ref new Exception(E_INVALIDARG)
. At least this way the error manifests in the managed debugger, and the message is descriptive.

I've been having this problem a lot with a UWP Windows 10 app on Visual Studio 2019...for me the reliable workaround is to bump the Build number in the Package.appxmanifest file (Packaging tab). It's a huge pain...really hope Microsoft will sort this out soon
