Visual Studio Not starting correctly

If you experience visual studio is not loading correctly and notify you about a package installation error or package load error

Please open an administrative CMD window and navigate to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE and run these commands:

1.devenv.exe  /safemode

2.devenv.exe  /resetskippkgs

3.devenv.exe  /installvstemplates

4.devenv.exe  /resetsettings

5.devenv.exe  /resetuserdata

these commands are not related to each other so you can issue one command and check is the problem is solved or not. For my case

devenv.exe  /resetuserdata  This command restart the whole visual studio environment and you need to login to the developer account.
