I am using Windows 7 Professional x64. When trying to turn some features on the following error occurs, and I am unable to install the features:
"An error has occurred. Not all of the features were successfully changed"
I am a user with admin rights (as someone mentioned here the problem being non-admin user).
I am trying to turn on "Application Development Features" like .Net Extensibility and ASP.Net under "World Wide Web Services".
After Windows tries to turn these features on, I receive the error message above.
What might be causing this problem, and how can I get these features installed?
