Visual Studio Error
I have been able to successfully build Hololens applications. However I have installed all the tools and am attempting to now build them on a different machine. I have followed the same steps as originally but now when attempting to deploy to the emulator I am getting the following error message:
Activation of the Windows Store app 'DestinyViz_sx6pycx103f58!App' failed with error 'Windows was unable to communicate with the target application. This usually indicates that the target application's process aborted. More information may be available in the Debug pane of the Output window (Debug->Windows->Output)'.
The program '[2904] Destiny Visualization.exe' has exited with code -1073741189 (0xc000027b).
My emulator starts up fine, it is currently running. I am deploying the app using "release" "x86" and "hololens emulator" as my settings.
Any help or advice would be very appreciated. Thank you.

So reinstalling visual studio and using the old unity beta (not the current .14) seems to have resolved the issue. I'm not sure which of those two things was acting up but reinstalling fixed the issue. Thank you for your assistance.

It might fail again just try to debug again
Also are you deploying in release or debug. I have only had this issue with debug builds
Thanks

I am deploying in release. I will try your suggestion.
Trying the steps you suggested did not resolve my issue.
What is different between the two machines? Is there less free disk space or memory available on the second machine?

The first machine is my personal laptop, the second machine is a desktop in the lab I work in. It has more memory and more free disk space than my laptop.
When attempting to deploy directly to the hololens I get a similar error:
"Unable to activate Windows Store app 'DestinyViz_sx6pycx103f58!App', The activation request failed with error "Could not find or load a type".
Does it deploy correct from the first machine?
Are they both running the same version of Windows?
Is it possible that you haven't installed the Unity UWP runtime (it's step 2)?
Also, can you double check that Visual Studio has the Universal Windows App Development Tools installed.

oh.... something else to try, set debugging to 'mixed (Managed and Native)' and then start with debugging. Maybe an exception is being thrown that will highlight the issue.

Yep it works when deploying on the first machine, for both the emulator and deploying to the hololens.
I do have all the appropriate files for visual studio installed. Both machines are running windows 10.
I installed the new unity version on the second machine which resulted in 1000's of errors and have since reverted back to the earlier version. I'm starting to think this may somehow be the cause as the newer version of unity also came with a new UWP file to install. When I build the scene out from unity I'm using Windows Store, Windows 10SDK, D3D and Developer and C# options. With the appropriate boxes checked in the build settings for Holographic SDK
Is your hololens in developer mode?
Hololens home screen --> Settings --> Updates --> For Developers
Can you validate that the software needed is installed..
Even if it is I would try to reinstall all the tools again. depending on if i was having other visual studio issues i might run a repair on visual studio, and maybe try to reinstall update 2.
Yes the hololens is in developer mode and developer mode is also enabled on both machines.
Enabling that debugging option that @Patrick recommended has been very helpful as it has given me much more detailed output. It seems that there are a lot of files in the windows\system32 folder that cannot be found or accessed. I'm not sure exactly what to do to solve those issues but it's definitely more information than I had before.
Stuff like in the attached
I also want to say thanks for all the help and your patience, I am not a computer science person, I'm simply a student who works in a lab and has been allowed to work with the hololens because of my previous work in Unity and Computer Animation (I'm an animation major).
I guess I'll try reinstalling everything from scratch. I will report back when I am done to state whether or not that fixed the problems.
