If you are writing a Window Store App on Windows 8, you might encounter a problem with Visual Studio where your license might be expired.
The error message would go like this
“Unable to active Windows Store app. The activation request failed with error. This app failed to launch because of an issue with its license. Please try again in a moment.
See help for advice on troubleshooting the issue”
There are 2 ways you can try to attempt to solve this problem.
Step 1:
1. Delete your debug,bin,obj and bld folders
2. Right click and uninstalled your original application which you encountered the problem with in the first place
3. Attempt to rebuild and redeploy your application
Step 2:
1. Unregistered your license by running “Unregister-WindowsDeveloperLicense” in an elevated PowerShell window
2. Restart your Machine
3. Start Visual Studio and attempt to replicate the problem
4. Use the dialog to get the a new developer license
5. Right click and uninstalled your original application which you encountered the problem with in the first place
6. Attempt to rebuild and redeploy your application
Just one question – Where are the debug, bin, obj and bld folders located?
go to documents->Visual studio 2012->projects->your project name folder->here two files will be available 1. Your file name.sln and 2.your file name folder. Inside the folder you will find bin, obj folders in it…
Just delete bin, service references and obj folders from the project folder. Clean solution and build it once. This error will go off…..
First technique worked well for me… 🙂
