I'm trying to update a Windows 8 app using Visual Studio 2013 (on Windows 10), but I can't seem to acquire a developer license. When I click "Project -> Store -> Acquire developer license" it just opens up the control panel on the "For developers" section where Developer mode is already enabled. (The same thing happens when I run Show-WindowsDeveloperLicenseRegistration in PowerShell.). Without the license I'm not able to create store packages. Hopefully someone has an idea.
The solution was to increase the version number in the manifest and clean/rebuild the project.
