Run Visual Studio in the context of an administrator account

If visual studio displays the error "... run Visual Studio in the context of an administrator account" a simple fix can be made:
1) Goto C:\Program Files (x86)\Common Files\Microsoft shared\MSEnv
2) Find the file VSLauncher.exe
3) Right click on it, select Properties, and then the Compatibility tab
4) Check the box for Run this program as an administrator

From now on when a solution file is opened the visual studio runs in the context of an administrator.

The same procedure must also be made for any shortcut to visual studio that you may have.
