Problems with Vs2013 Express for Windows RRS feed

  • Question

  • Hello, I'm new to .Net and C# programming and this is my first question on the forum.

    I've just installed Vs2013 Express for Windows and created Blank App(Xaml), first of all designer failed to load and it threw

    System.Runtime.InteropServices.COMException , The app didn't start. (Exception from HRESULT: 0x8027025B).

    If you aren't lazy to read, here's the full exception:

    Well after a bit of unsuccessful googling I tried launching application in debug mode, without changing any code and got:

    An unhandled exception of type 'System.Exception' occurred in App2.exe

    Additional information: Could not read key from registry (Exception from HRESULT: 0x80040150 (REGDB_E_READREGDB))

    and then:

    An issue in app process caused it to fail to activate. This process threw one or more or more exceptions.

    I'm using Windows 8.1 and have no problems with Vs2013 express for desktop.

  • Hi,

    May be some problem in your OS. You can try to reinstall Win8.1 and VS2013. Before reinstall, you should clean up the VS2013 installation.
