I am trying to develop Win 8 Store apps using VS Express 2012. Oddly, when I recently went back to look over the initial "Hello World" apps which I had built in the initial "30 Days to Build a Store App" campaign, these initial apps no
longer run in debug. An error message pops up which says:
"Unable to activate 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."
Now after spending quite some effort on developing a real app, I am getting the same error message. Is there something I can do to be allowed to develop an app for more than a couple of weeks?
Make sure your developer license is up to date. It will expire after 30 days. Visual Studio should re-request it for you automatically, but if not then you can do so manually from an elevated powershell prompt:
