How to fix "Unable to activate Windows Tailored application" on Win8 - visual-studio

I get "Unable to activate Windows Tailored application" error in Metro app when I'm running it under debugger of Visual Studio 11. I installed Windows 8 x64 Developer Preview on my Dell E6510 laptop.
I googled it and found out many people saying it happens when screen resolution is smaller than 800x600 but it's 1920x1280 in my case.
The app itself contains nothing. It's just empty wizard created application which is nothing but windows with black background.
Any ideas? It seems like very common issue.

The solution was quite bizarre but I figured it out.
It turns out not a single Metro application works under Administrator account including my apps. I'm talking about built-in Administrator account that is disabled by default (but which I enabled).
It gives "Access denied" error so I suspect it's somehow related to the way WinRT COM objects were registered or something like that. Go figure.
I hope somebody from Microsoft is reading this.

Best solution is to wait 2 weeks for the next release. The developer preview is full of fun bugs like this. I've seen this error caused by invalid app.xaml. Double check that you really haven't changed anything. I've also seen this error sometimes resolved by rebooting. Have fun!

blank window when installing visual studio on windows 10

I have a Windows 10 64-bit PC (fresh install, not an upgrade).
When I run the setup file (web or offline alike) in order to install Visual Studio (2013 or 2015, Community edition), all I get is a small black rectangle on the screen (which I later found out that this is actually the title of the setup popup window), without the actual window of the installation.
I have tried it also after a reboot, and with various "versions" of the installation files (web, iso, standalone), but it's always the same situation.
What can I do about it? VS is my main development tool and I really need it on this computer as soon as possible.
Similar problem here. Program install ok but display blank screen after launched.
Problem solved when I changed my Nvidia graphics's global 3D setting to integrated graphics.
Right click desktop
Select Nvidia Control Panel
Select Manage 3D Settings
Under preferred graphics processor, select integrated graphics.
Apply.
If you are using a laptop with an external monitor, try unplugging it and using your primary monitor to launch. This worked for me. Laptops often have dual graphics cards and I believe we're hitting some issue with the way the Installer for VS was written (likely WPF)
Once I launced it and started the installation, I could safely plug my monitor in and it kept working properly.
I'm using an AMD GPU, It was a blank white screen but when I hover the mouse over it, I can see the text events
By the way
I went to my AMD Radeon Settings and saw that vs_installershell.exe and vs_setup_bootstrapper.exe were added automatically to the Switchable Graphics list
they were with Not Assigned Option which usually is like High Performace Option
means It would run it with my ATI GPU.
So I clicked on them
Selected Power Saving Option (to work with my Intel GPU)
Which worked and I can see the window of visual studio installer back
after restarting visual studio installer for sure.
whether is your graphics card, just turn on power saving for it.
Had the same issue. Since this topic is not accept any answare, there is one from https://developercommunity.visualstudio.com/content/problem/150888/visual-studio-installer-shows-blank-screen.html
Try to open installer as Admin.
You will probably have blank screen. Do not close it!
Open installer once more.
Hope it help other people with same issue.
the same thing happened to me, i didn't do anything i just waited for it and it started showing it's status, i suggest you close other running programs to avoid conflicts and performance hindering, and try it again.
This seems like a very shoddy issue. I've run into this problem too, and I tested all solutions that I came across online. These all work:
Running the installer as administrator, which is a blank screen. Leave it open and run a second instance of the installer, which will not be blank (doesn't need to be run as administrator the second time.
Changing screen settings so that the laptop screen is not being used.
Downloading the AMD Settings application, and setting vs_installershell.exe to run on powersaving mode. Restart the installer after saving the settings.
Use a default graphics driver instead of the AMD one.
I had the the same problem in my laptop. The temporary solution is: start the installer only without the battery, if installer starts you can connect the cable, it works fine.
I had to run integrated graphics rather than my Nvdia. That solved it for me.
Remember to change it back when programming in OpenGL and DirectX otherwise you may get a list of messages staying that nothing works.
I had the the same problem in my laptop. The work around is, in device management, remove the amd graphics or start the installer only with battery.

Windows Phone 8.1: App crashes in fast app switcher when not attached to debugger

I have been developing this app for quite a long time, and have had little or no issues. But when I decided to test it without the debugger attached, it caused problems with the fast app switcher. Whenever I switch the app with fast app switcher (or by pressing Start button), it causes the app to crash.
I am using VS2015 and tried enabling break for all exceptions, but still nothing happens while debugging, so I can't understand what the actual problem is.
Any ideas how can I solve this??
P.S. There seem to be a solution for this in this thread: Fast App Resume crashing on WP8.1 when not attached to debugger, but it is intended for Windows Phone 8 and doesn't match with the 8.1 api. Any similar solutions for WP8.1??
have you tried to implement the NavigationHelpers in your app ?

I think that may help you :)

App approved, but crashes

I have made a Windows Phone app (for WP7.1) that uses BackgroundAudio for streaming, nothing too complicated. It was approved and made available for download in the store. However it no longer works, i.e. the app worked in debug+release when run from VS2012, and I assume the .xap I uploaded worked since microsoft approved it (they rejected it once and I was able to reproduce and fix the bugs they reported).
When downloaded the app simply bails on load on WP8 (lumia 820) i.e. flips back to the tiles immediately.
On WP7 (lumia 800) but the playbutton ignores input, however it downloads and displays the playlist, so some kind of functionality+network connection works.
I have tried the basics: installing using the application-deployment tool (app working), running the "Store Test Kit" which reports some slowdowns in the UI animations, but nothing serious (I hope).
Any ideas how to reproduce ".xap approved and downloaded from store but not working" or getting debug info from the phone without VS? Or any other things i can try out?
Every time your app crashes it will be logged and reported on your Windows Phone Dev Center Account. Just go in there and export the details to excel. Get the stack trace and put it in here. Maybe we can help.
The very first thing i can tell you is the opening page has some exceptions and that too it doesn't go well with some phones. Seriously there are concerns when a wp7 app is ported on wp8 device and vice-verse. To the extent of my knowledge there might be some binding issues. make sure you got the binding class to be public. And just as #AMR mentioned go the dev center and export the stacktrace. Try resolving them. Moreover if an app get certifies, it doesn't mean it is completely error free. The tests are limited to very coomon errors only.

The parameter is incorrect exception

I'm working on a Windows Phone 7.1 project and got most of my work done and decided to add to the project the images for my tiles (62x62 and 173x173 PNGs) plus the JPG file for the splash screen (SplashScreenImage.jpg 480x800).
Before adding these images to the project my project was running fine! After adding them and setting the tiles images to the 2 new files, my project still builds ok, but when running on the 7.1 simulator (my acer laptop doesn't have hardware assisted virtualization enabled in order to run the wp8 emulator) the app crashes when trying to load MainPage with "The parameter is incorrect" exception (in the Application_UnhandledException handler).
I've been trying to find a solution on the web for the last 1-2 days, found few mentions of this error and few possible causes, but none of my findings helped so far. The exception doesn't say anything helpful and it's getting really frustrating considering that most of the serious work is done and I'm very close to releasing the app to the marketplace.
Did anybody run into this issue before? Any ideas what could have gone wrong and how I could solve this exception? Any help is much appreciated!
Thank you in advance!

Whenever I wish to change the Splashscreen and other images, here is what I do:
Locate the file on disk using Windows Explorer.
Open the file using some image editor (I use Paint.NET)
Remove the default image and replace with your image maintaining the dimensions.
Save the image and return to Visual Studio.
Rebuild the entire project.
This works seamlessly without any errors. ;)

Silverlight and Windows 8 Consumer Preview working?

The Windows 8 Consumer Preview is now available. It is known that Silverlight will not run in metrostylemode, but with legacy/desktopmode it is working?
Anything unusual to keep in mind?
Are you able to access Silverlight applications?
(sorry for my bad english)
I have an medium sized SL5 LOB RIA Services app that runs OOB and it is working fine on windows 8 CP. The only thing that did not worked as I expected is that the on-screen keyboard do not show when I enter a text field. probably there is a way to p/invoke this but it would be nice if this happens by default.
I don't think there was anything new posted to that effect (but then the story was already explained in Dev Preview). It basically works the way you describe in Beta.
Apparently you can add a meta tag which causes the metro browser to prompt the user, but I have not yet tested.
