Go to the setup.exe of the program that you want to install>Right Click on
it> Select "Run as Admin"

The error that you are getting usually happens if your pc is infected with virus. You can try to download the Windows Installer Clean up Utility by searching it on the internet and install it in your pc to correct this problem. Also try to scan your computer with Antivirus software to remove the infections. Download malicious software removal tool from this link - http://www.microsoft.com/downloads/d...displaylang=en

First click on Start and then go to Run and type net start dhcp and press Enter and check the results. Also see if there is any problems with the UAC / Premissions issue, just check in control panel User Accounts. Can you tell us what is the startup type for Diagnostic Policy Service? Did you check the Event Log for information on why the service does not start on boot?
