The FIX:  Start Visual Studio in Admin mode

Steps:
1. Click on Start Menu > All Programs > Microsoft Visual Studio 2010
2. Right-Click on “Microsoft Visual Studio 2010” and go to the Properties
3. Click on the Compatibility tab
4. Click on box next to “Run this program as an administrator”. You’d find it in the Privilege Level section (See below)

Note:

> You need to have Administrator privileges to do this

> Once configured this way, you would get a UAC prompt when you open the Visual Studio IDE. It’s better than Right click and selecting run in admin mode every time you want to run the IDE.
