Installing Sitefinity and creating projects with Sitefinity Project Manager under Windows 2008 can be done by users with administrative rights to files and virtual directories.
To run the setup, right-click the .exe file and select Run as Administrator
from the menu.
Once Sitefinity is installed, the Project Manager is installed by default in: C:\Program Files\telerik\Sitefinity3.x. A shortcut to it appears under the Windows Start Menu> Programs> telerik> Sitefinity 3.x.
To start the Project Manager as an Administrator:
1. Right click on the Browser icon and select Run as Administrator
2. In the browser window which opens, paste the location of the Project Manager (i.e. C:\Program Files\telerik\Sitefinity3.x).
Let us know if you encounter any problems.
All the best,
the Telerik team
