Failing to find AppxManifest.xml

Hi!

I'm trying to build a debug build on my local machine, upon build finishing it will show this error:

My build is failing everytime with following error:

Code (CSharp):

1. System.IO.DirectoryNotFoundException: Could not find a part of the path '...........\build\bin\x64\Debug\AppX\AppxManifest.xml

 

Hey i'm trying to build a Universal Windows Platform (UWP) project from Unity, the build fails with the following errors:

Code (CSharp):

1. BuildFailedException: Deployment failed. Output:
2. System.IO.DirectoryNotFoundException: Could not find a part of the path 'G:\Unity\Projects\MATRIX UWP\Project\DRIFT MATRIX\Build\TestBuilds\TestBuild1\build\bin\x64\Debug\AppX\AppxManifest.xml'.

2019.1.0f2

 

Had the same problem. You are right, it works PERFECTLY, so tks man!
I think the error was thrown because I don't have checked "developer mode" on "use developer feature" of windows 10 settings panel - so pressing build is enough, "build and run" can't run the app.

 

this is happening for me on LTS 2019 and the latest 2020

It is trying to find the AppXManifest file inside a subfolder called AppX that is not created in the build process

To reproduce this just create a blank UWP project and try to 'build and run'

 

Worked for me as well, thank you so much!

 

I have Unity Hub 2.4.3. Unity 2020.3.8f1 (LTS) and if I make a blank 2d project and hit "build and run", it works fine -- but I notice that a new project uses the "PC, Mac, and Linux Standalone" build settings. My existing project defaults to "Universal Windows Platform" (I don't believe that I changed that, and I don't remember if there was an option while setting up my project.) I can fix my existing project by switching the build to "PC, Mac, and Linux Standalone" as long as I make sure my architecture is x86.

However, if I set it to x86_64, I get the same error as the "Universal Windows Platform" build:

 BuildFailedException: Deployment failed.

Output:System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\ehyrk\bin\build\bin\x64\Release\AppX\AppxManifest.xml'.

The AppX folder doesn't exist. It makes an "exe" file in the Release folder, but the executable doesn't work because of a missing dll.

I'm not sure why this is happening, but it might help the people above. I find it really interesting that this is happening and I can probably dig into why x86_64 build is failing in a bit.

 

Uninstalling and reinstalling Visual Studio with pretty much every option that (in my mind) could plausibly be related installed, I can now build using x86_64 platform for Windows using "PC, Mac & Linux Standalone". I was using the same Visual Studio that I have been using for non-game development C++ and must have been missing something Unity needed. (It isn't clear to me what was missing, since I had most optional packages of Visual Studio already installed, and testing one checkbox at a time wasn't an option since my time is limited.)

Getting "Universal Windows Platform" build to work was much more difficult. Even though I installed a number of Windows 10 SDKs and messed around with a lot of options, what finally got it to work was sort of silly. I turned on "Developer Mode" in settings:
